Let us go up against Judah, and trouble it, and let us conquer it for ourselves and set a king in the midst of it, even the son of {g} Tabeal:

(g) Who was an Israelite, and as it seems, enemy to the house of David.

Wesley's Notes

7:6 Let us - Break their power and kingdom and subdue it to ourselves.

son of Tabeal-unknown; a Syrian-sounding name, perhaps favored by a party in Jerusalem (Isa 3:6, 9, 12).

Matthew Henry's Concise Commentary

7:1-9 Ungodly men are often punished by others as bad as themselves. Being in great distress and confusion, the Jews gave up all for lost. They had made God their enemy, and knew not how to make him their friend. The prophet must teach them to despise their enemies, in faith and dependence on God. Ahaz, in fear, called them two powerful princes. No, says the prophet, they are but tails of smoking firebrands, burnt out already. The two kingdoms of Syria and Israel were nearly expiring. While God has work for the firebrands of the earth, they consume all before them; but when their work is fulfilled, they will be extinguished in smoke. That which Ahaz thought most formidable, is made the ground of their defeat; because they have taken evil counsel against thee; which is an offence to God. God scorns the scorners, and gives his word that the attempt should not succeed. Man purposes, but God disposes. It was folly for those to be trying to ruin their neighbours, who were themselves near to ruin. Isaiah must urge the Jews to rely on the assurances given them. Faith is absolutely necessary to quiet and compose the mind in trials.
