For the Lord had made them hear, in the camp of Syria, the noise of chariots, and of horses, and of a very great army, and they said one to another: Behold the king of Israel hath hired against us the kings of the Hethites, and of the Egyptians, and they are come upon us.

seeing Jehovah hath caused the camp of Aram to hear a noise of chariot and a noise of horse, a noise of great force, and they say one unto another, 'Lo, the king of Israel hath hired against us the kings of the Hittites, and the kings of Egypt, to come against us.'

For the Lord had made the sound of carriages and horses, and the noise of a great army, come to the ears of the Aramaeans, so that they said to one another, Truly, the king of Israel has got the kings of the Hittites and of the Egyptians for a price to make an attack on us.

For the Lord had made the host of the Arameans to hear a noise of chariots, and a noise of horses, even the noise of a great host; and they said one to another: 'Lo, the king of Israel hath hired against us the kings of the Hittites, and the kings of the Egyptians, to come upon us.'

For indeed, the Lord had caused them to hear, in the camp of Syria, the sound of chariots and horses, and a very numerous army. And they said one to another: "Behold, the king of Israel has paid wages to the kings of the Hittites and of the Egyptians against us. And they will overwhelm us."

It is a matter of no importance whether we say that the miracle by which God now performed deliverance for Samaria consisted in a mere illusion of the sense of hearing (compare 2-Kings 6:19-20); or whether there was any objective reality in the sound (compare the marginal references).
The king of Israel hath hired - The swords of mercenaries had been employed by the nations bordering on Palestine as early as the time of David 2-Samuel 10:6; 1-Chronicles 19:6-7. Hence, the supposition of the Syrians was far from improbable.
The kings of the Hittites - The Hittites, who are found first in the south Genesis 23:7, then in the center of Judea Joshua 11:3, seem to have retired northward after the occupation of Palestine by the Israelites. They are found among the Syrian enemies of the Egyptians in the monuments of the 19th dynasty (about 1300 B.C.), and appear at that time to have inhabited the valley of the Upper Orontes. In the early Assyrian monuments they form a great confederacy, as the most powerful people of northern Syria, dwelling on both banks of the Euphrates, while at the same time there is a second confederacy of their race further to the south, which seems to inhabit the anti-Lebanon between Hamath and Damascus. These southern Hittites are in the time of Benhadad and Hazael a powerful people, especially strong in chariots; and generally assist the Syrians against the Assyrians. The Syrians seem now to have imagined that these southern Hittites had been hired by Jehoram.
The kings of the Egyptians - This is a remarkable expression, since Egypt elsewhere throughout Scripture appears always as a centralised monarchy under a single ruler. The probability is that the principal Pharaoh had a prince or princes associated with him on the throne, a practice not uncommon in Egypt. The period, which is that of the 22nd dynasty, is an obscure one, on which the monuments throw but little light.

The Lord had made the - Syrians to hear a noise - This threw them into confusion; they imagined that they were about to be attacked by powerful auxiliaries, which the king of Israel had hired against them.

For the Lord had made the host of the Syrians to hear a (f) noise of chariots, and a noise of horses, [even] the noise of a great host: and they said one to another, Lo, the king of Israel hath hired against us the kings of the Hittites, and the kings of the Egyptians, to come upon us.
(f) Thus God needs no great preparation to destroy the wicked. Though they are many he can scatter them with a small noise, or shaking of a leaf.

For the Lord had made the host of the Syrians to hear a noise of chariots, and a noise of horses, even the noise of a great host,.... Or of many armies, as the Targum; either in the air by the ministry of angels; or the Lord so wrought upon their imagination, that they fancied they heard such noises; or he caused such noises in their ears:
and they said one to another, lo, the king of Israel hath hired against us the kings of the Hittites; one of the nations of the Canaanites, and may be here put for the whole of those that remained, and who lived upon the borders of the land of Israel; though Josephus (y) has it, the kings of the isles; that is, of Chittim, see Jeremiah 2:10.
and the kings of the Egyptians, to come upon us; Egypt being now divided into petty kingdoms; or else the governors of the several nomes or districts of it are here meant: for the king of Israel to hire these kings was very unlikely in his present circumstances; but those unreasonable things, in their panic, their imaginations suggested to them.
(y) Ut supra, (Antiqu. l. 9. c. 4.) sect. 5.

the Lord had made the host of the Syrians to hear a noise of chariots--This illusion of the sense of hearing, whereby the besiegers imagined the tramp of two armies from opposite quarters, was a great miracle which God wrought directly for the deliverance of His people.

Hittites - Under which name (as elsewhere under the name of the Amorites) he seems to understand all the people of Canaan. For though the greatest number of that people were destroyed, yet very many of them were spared, and many of them upon Joshua's coming, fled away, some to remote parts, others to the lands bordering upon Canaan, where they seated themselves, and grew numerous and powerful. Kings - Either the king of Egypt, the plural number being put for the singular, or, the princes and governors of the several provinces in Egypt.
