And in the time of his distress did he trespass yet more against the LORD: this is that king Ahaz.
In the time of his distress did he trespass yet more. This infatuated king surrendered himself to the influence of idolatry, and exerted his royal authority to extend it, with the intensity of a passion, with the ignorance and servile fear of a pagan (2 Chronicles 28:23: cf. Jeremiah 44:16-18; Hosea 2:5), and a ruthless defiance of God (2 Kings 16:10-20).
This is that king Ahaz. The original, 'this king Ahaz,' is more terse and pointed.
