18 Yahweh said to Joshua, "Stretch out the javelin that is in your hand toward Ai, for I will give it into your hand." Joshua stretched out the javelin that was in his hand toward the city.

And the Lord said unto Joshua, etc This passage shows, that owing either to the strong fortifications of the city, or the valor of its inhabitants, or the trepidation of the Israelites, the victory was difficult, since God promises that he himself would take it by the lifting up of a spear. Had success been beyond doubt, the symbol would have been superfluous; their minds must therefore have been anxious and perplexed, since the Lord, to prevent them from fainting, raises up a banner of confidence in the hand of Joshua. It is true, indeed, that shortly after a different motive for raising the spear is mentioned, when it is said, that in this way a signal was given to the ambuscade, which accordingly rushed forth. But if it really was so used as a signal, it will scarcely do to regard the spear as a manifestation of the victorious power of God dispelling all doubt. Still, however, as it is not expressly said that the spear was the cause which brought forth the soldiers who had been placed in ambuscade, the truth may be that they came forth of their own accord, either because it was the suitable time, or because the shouting and noise made them aware that the battle had actually commenced. For it is scarcely possible to believe that the spear was seen by them, when we consider the long space which intervened, and more especially that Joshua was standing in a valley. Moreover, if we hold that the lifting up of the spear, though intended for a different purpose, had also the effect of inspiring them with additional courage, there will be no absurdity in it. This much ought to be regarded as certain, first, that by this solemn badge they were rendered more certain of the happy issue of the battle; and secondly, that Joshua had no other intention than to incite his troops according to the command of God. For it is at last added, that Joshua did not draw back his hand until the city was taken, the enemy everywhere destroyed, and the war itself terminated. Hence it appears that he exhibited it in the middle of the conflict as an ensign of triumph, that the Israelites might have no doubt of success. For although he ordered them to engage and use their arms bravely, he at the same time distinctly declared that they had already conquered. The course of the battle is rendered somewhat obscure by the same thing being told twice, but the substance is sufficiently plain. The children of Israel retreated feigning fear, and the battle had not actually commenced before the inhabitants of Ai were precluded from returning and defending their city. After the two armies had come to close quarters, the ambuscade arose and made such haste that the flames of the conflagration were rising from the city when the enemy turned their backs. From this we may infer that the city was in the possession of the Israelites, but that the chief slaughter took place when those who were in the city came forth to take part in the battle, because the inhabitants, hemmed in on all sides, found resistance and flight equally unavailing. They were thus seized with despair, and, huddled together in a narrow space, were everywhere cut down. The statement, that the slaughter did not take place in the city before those who had feigned flight returned, I understand to mean, that the whole troops uniting their forces rushed in, seized the prey, and slew all who might have been left. If any one objects that the city was burnt while the battle was going on, I answer, that the fire was indeed applied so as to let both armies know that the city was in possession of the Israelites, but it was not actually destroyed by fire. It was not practicable in a moment of time to seize and carry off the booty, nay, to bring the vessels and a large part of the property without the walls; and it would have been absurd voluntarily to destroy spoils which God had granted. We see, then, that the first fire was not kindled for the purpose of destroying the whole city, but was merely a partial conflagration giving intimation of its capture, and that the Israelites entered at the open gates without bloodshed or a struggle. This is confirmed shortly after, when the burning is ascribed to Joshua himself, not only because it was burnt under his command, but because he was careful, after returning from the battle, to see that it was utterly destroyed; as it is immediately added that he made it a heap of stones in order that it might be a perpetual desolation.

1 - Ai and its apparently tributary town Bethel, thus subjected to a fearful destruction, were situated about twelve miles north from Jerusalem, and seventeen miles west-north-west from Jericho, and had previously been brought under the notice of the Israelites in very different circumstances. For they had read in the interesting narrative of Moses how Abraham had pitched his tent on a mountain, "having Bethel on the west and Hai (Ai) on the east; and there he built an alter unto the Lord, and called upon the name of the Lord," (Genesis 12:8; Genesis 13:3;) and how Bethel, formerly called Luz, had changed its name, because Jacob, on awaking out of his wonderful dream, had declared it to be "none other but the house of God," and "the gate of heaven." (Genesis 28:11-19.) Notwithstanding of the doom pronounced and executed upon Ai, it appears to have been rebuilt, was occupied by the Benjamites after their return from the captivity, (Nehemiah 7:32; Nehemiah 11:31; Ezra 2:28,) is mentioned by Josephus under the name of Aina, and still exhibits some indications of its site. -- Ed.
No doubt Joshua had ascended the heights, most likely those to the north of the valley, so as to separate himself from the flying Israelites on the lower ground, and to be visible to the men in ambush behind the city. He now, at the command of God, gives the appointed signal to the ambush.
Stretch out the spear - It is very probable that Joshua had a flag or ensign at the end of his spear, which might be easily seen at a considerable distance; and that the unfurling or waving of this was the sign agreed on between him and the ambush. (see Joshua 8:13, and the preceding observations on Joshua 8:1 (note), observation 6); and on seeing this flag or ensign unfurled, the men who lay in ambush arose and entered the city, making the fire previously agreed on. See Joshua 8:8.
And the LORD said unto Joshua, (h) Stretch out the spear that [is] in thy hand toward Ai; for I will give it into thine hand. And Joshua stretched out the spear that [he had] in his hand toward the city.
(h) Or, lift up the banner to signify when they should invade the city.
And the Lord said unto Joshua, stretch out the spear that is in thy hand towards Ai,.... On which was a flag, as Abarbinel and Ben Melech think; and which is not improbable, and served for a signal for the ambush to come out and seize the city, as both they and Jarchi observe, as well as a signal also to the army of Israel to prepare to turn and face about, and engage with the enemy; though they did not actually do this until they saw the smoke of the city, Joshua 8:21,
for I will give it into thine hand; of which the stretching out of his spear seems also to be a confirming sign to him, and which he kept stretched out until all the inhabitants of Ai were destroyed, Joshua 8:26,
and Joshua stretched out the spear that he had in his hand toward the city: and therefore must turn himself towards it; and it is highly probable that at the same time there was a full stop of the army, and that they immediately turned or prepared to turn about.
Joshua stretched out the spear that he had in his hand toward the city--The uplifted spear had probably a flag, or streamer on it, to render it the more conspicuous from the height where he stood. At the sight of this understood signal the ambush nearest the city, informed by their scouts, made a sudden rush and took possession of the city, telegraphing to their brethren by raising a smoke from the walls. Upon seeing this, the main body, who had been reigning a flight, turned round at the head of the pass upon their pursuers, while the twenty-five thousand issuing from their ambuscade, fell back upon their rear. The Ai-ites surprised, looked back, and found their situation now desperate.
Stretch out the spear - This was, either, for a sign to his host present with him, to stop their flight, and make head against the pursuers: or, for a signal to the liers in wait, or, as a token of God's presence and assistance with them, and of their victory.
