17:18 Seeing he despised the oath by breaking the covenant, when, lo, he had given {m} his hand, and hath done all these [things], he shall not escape.
(m) Because he took the name of God in vain, and broke his oath which he had confirmed by giving his hand: therefore the prophet declares that God would not permit such perjury and infidelity to escape punishment.
17:18 Given his hand - Solemnly confirming the oath.
17:11-21 The parable is explained, and the particulars of the history of the Jewish nation at that time may be traced. Zedekiah had been ungrateful to his benefactor, which is a sin against God. In every solemn oath, God is appealed to as a witness of the sincerity of him that swears. Truth is a debt owing to all men. If the professors of the true religion deal treacherously with those of a false religion, their profession makes their sin the worse; and God will the more surely and severely punish it. The Lord will not hold those guiltless who take his name in vain; and no man shall escape the righteous judgment of God who dies under unrepented guilt.
