And Israel sent messengers. The second narration, which I have subjoined from Deuteronomy, is the fuller; nevertheless, a question arises from it, for what reason this embassy was sent to king Sihon, whose kingdom was already devoted to the Israelites: for it seems to be altogether inconsistent to offer conditions of peace when war is decreed. God commands His people to take up arms: He declares that they shall be victorious, so as to occupy the land of Sihon by right of war; what, then, can be more absurd than to request of him that they might pass through his land in peace? If this attempt were made by Moses without the command of God, such an excess of kindness was not devoid of guilt, inasmuch as it was an act of much temerity to promise what God had appointed otherwise. But, if we should say that the messengers went with the authority, and at the command of God, under what pretext shall the deceptiveness of the act be excused? for it is very improper to flatter with soothing words and promises those whom you have destined to destruction. The conclusion I come to is, that although the event was not unknown to God, still the embassy was sent, nevertheless, by his command and decree, in order to lay open the obstinate ferocity of the nation. But, since the secret judgments of God far surmount our senses, let us learn to reverence their height; and let this sober view restrain our boldness like a rein, viz., that although the reason for the works of God be unknown to us, still it always exists with Him. God knew that the messengers would speak to the deaf, and yet it is not in vain that He bids them go; for, since the kingdom of Sihon was not properly included in the promised land, it was not lawful for the children of Israel to make war upon it until they had been provoked by an unjust refusal. Thus, then, I connect the history. Before they had been assured at God's command of the event, and the victory, they sent the messengers, who demanded that a pacific passage should be accorded to them; and that then the permission to have recourse to arms was granted. If any prefer to think that, before Moses attempted to preserve peace, he had been made acquainted with all that would occur, I will not contend the point; but I deem it more probable that he had expectations of the peace which he sought, because the judgment of God had not yet been declared. If, therefore, Sihon had allowed himself to be propitiated, Moses would never have dared to deal with him as an enemy; but, he rather simply and honestly promised peace, which he intended to preserve; God, however, had otherwise appointed, as the event presently shewed. Still He was not inconsistent with Himself, or variable, in sending the messengers to an irreclaimable and obstinately perverse man; for thus was all excuse taken away when he had voluntarily provoked to war a people who were ready and willing to maintain peace and equity. But rather may we see in this history, as in a glass, that, whilst God earnestly invites the reprobate to repentance and the hope of salvation, He has no other object than that they may be rendered inexcusable by the detection of their impiety. Hence is their ignorance refuted, who gather from this that it is free for all promiscuously to embrace God's grace, because its promulgation (doctrina) is common, and directed to all without exception; as if God was not aware of what Sihon would answer when He would have him attracted to equity by friendly and peaceful words; or as if, on his free will, the purpose of God was suspended as to the war, which was soon after carried forward by His decree. But inasmuch as what is here briefly recorded, would be obscure in itself, we must explain it by the other narrative, where it is thus written, --

And Israel sent messengers unto Sihon king of the Amorites,.... Who were one of the nations of the Canaanites, and a principal and powerful one, and who were devoted to destruction, and their land designed for the people of Israel; see Genesis 15:16, at this time Sihon was their king, to whom Moses, in the name of Israel, sent a very peaceable message from the wilderness of Kedemoth, which lay near his country, Deuteronomy 2:26,
saying; as follows.

Sihon went with his forces against Israel, out of his own borders, without provocation, and so ran upon his own ruin. The enemies of God's church often perish by the counsels they think most wisely taken. Og, king of Bashan, instead of being warned by the fate of his neighbours, to make peace with Israel, makes war with them, which proves in like manner his destruction. Wicked men do their utmost to secure themselves and their possessions against the judgments of God; but all in vain, when the day comes on which they must fall. God gave Israel success, while Moses was with them, that he might see the beginning of the glorious work, though he must not live to see it finished. This was, in comparison, but as the day of small things, yet it was an earnest of great things. We must prepare for fresh conflicts and enemies. We must make no peace or truce with the powers of darkness, nor even treat with them; nor should we expect any pause in our contest. But, trusting in God, and obeying his commands, we shall be more than conquerors over every enemy.

Israel sent messengers unto Sihon--The rejection of their respectful and pacific message was resented--Sihon was discomfited in battle--and Israel obtained by right of conquest the whole of the Amorite dominions.

Defeat of the Amorite Kings, Sihon of Heshbon and Og of Bashan, and Conquest of their Kingdoms.

Sent messengers - By God's allowance, that so Sihon's malice might be the more evident and inexcusable, and their title to his country more clear in the judgment of all men, as being gotten by a just war, into which they were forced for their own defence.
