Yea, though they have hired - Or better, "because or when they hinge among the pagan, now will I gather them;" i. e., I will gather the nations together. The sin of Israel should bring its own punishment. He sent presents to the king of Assyria, in order to strengthen himself against the will of God; "he thought himself secured by his league made with them; but he should find himself much deceived in his policy;" he had "hired among them" only; "now," ere long, very speedily, God Himself would "gather them," i. e., those very nations, not in part, but altogether; not for the help of Israel, but for its destruction. As though a man would let out some water from a deep lake ponded up, the water, as it oozed out, loosened more and more the barriers which withheld it, until, at length, all gave way, and the water of the lake was poured out in one wide wild waste, desolating all, over which it swept. It may be, that Assyria would not have known of, or noticed Israel, had not Israel first invited him.
And they shall sorrow a little for the burden of the king of princes - So great shall be the burden of the captivity hereafter, that they shall then sorrow but little for any burdens put upon them now, and which they now feel so heavy. "The king of princes" is the king of Assyria, who said, "Are not my princes altogether kings?" Isaiah 10:8. The burden of plained will then be the thousand talents of silver which Menahem gave to Pul, king of Assyria, to support him in his usurpation, and in order to pay which, he "exacted the money of Israel, even of all the mighty men of wealth, of each man fifty shekels of silver" 2-Kings 15:19-20.
If we adopt the English margin, "begin," we must render, "and they shall begin to be minished through the burden of the king of the princes," i. e., they shall be gradually reduced and brought low through the exactions of the Assyrians, until in the end they shall be carried away. This describes the gradual decay of Israel, first through the exactions of Pul, then through the captivity of Gilead by Tiglathpileser.

For the burden of the king of princes - The exactions of the Assyrian king, and the princes of the provinces.

Yea, though they have hired among the nations, now will I gather them, and they shall sorrow a little for the (h) burden of the king of princes.
(h) That is, for the king and the princes will lay upon them: and by this means the Lord brings them to repentance.

Yea, though they have hired among the nations,.... That is, lovers, as before; got into confederacies and alliances with the nations about them, thinking thereby to strengthen their hands, and secure themselves and their kingdom; particular regard may be had to the Egyptians, as distinct from the Assyrians, whom they privately engaged on their side to shake off the Assyrian yoke, or their obligation to send yearly presents to the Assyrian king:
now will I gather them; either the Assyrians against them, to invade their land, besiege their city, and take and carry them captive; or the Israelites in a body into the city of Samaria, and there be cooped up, and taken and destroyed, or carried captive; for this is not to be interpreted of the collection of them out of their captivity, as the Targum and Jarchi, but of the gathering of them together for their destruction:
and they shall sorrow a little for the burden of the king of princes; the tax or tribute imposed upon them by the king of Assyria, whose princes were altogether kings, Isaiah 10:8; and who used to be called king of kings, being at the head of a monarchy, which had many kings subject to it; as the kings of Babylon were afterwards called, Ezekiel 26:7; this may refer to the yearly present or tribute, which Hoshea king of Israel was obliged to give to the king of Assyria, which he was very uneasy at, and did not pay it, which drew upon him the resentment of the Assyrian king; and that sorrow and uneasiness which that tribute gave the king of Israel and his people were but little and small in comparison of what they after found; it was the beginning of sorrows to them: and so some render the words, "they began" (l); that is, to sorrow and complain "a little"; or this may refer to their burdens and oppressions when in captivity, which were laid upon them by the king of Assyria, and the princes, the rulers, and governors of the several places where the Israelites were carried captive: even the "few that shall remain" (m), as some render it; and not die by famine, pestilence, and sword. Kimchi and Ben Melech think there is a deficiency of the copulative and between king and princes; which is supplied by the Targum, and by the Septuagint, Vulgate Latin, Syriac, and Arabic versions, which read, "the king and princes".
(l) "incipient", Calvin; "ceperunt enim paululum", Junius & Tremellius, Piscator, Zanchius, Drusius, Tarnovius, so Ben Melech. (m) "et remanebunt pauci", Schmidt; a rad. "durare, permanere".

will I gather them--namely, the nations (Assyria, &c.) against Israel, instead of their assisting her as she had wished (Ezekiel 16:37).
a little--rather, "in a little" [HENDERSON]. English Version gives good sense: They shall sorrow "a little" at the imposition of the tribute; God suspended yet the great judgment, namely, their deportation by Assyria.
the burden of the king of princes--the tribute imposed on Israel (under Menahem) by the Assyrian king Pul, (2-Kings 15:19-22), who had many "princes" under his sway (Isaiah 10:8).

Gather them - I will assemble them together, that they may be taken and destroyed together. A little - For a while before their final captivity. The burden - The tribute laid on them by the king.
