Though they take the most binding form of oath, they do so only as a means of deceiving others.

The Lord liveth - Though they profess to bind themselves by Jehovah, as if they acknowledged him their God and only Lord, yet they swore falsely; for not believing in him, they took a false oath; one by which they did not believe themselves bound, not acknowledging him as their Lord. See on Jeremiah 4:2 (note).

And though they say, the Lord liveth,.... It might be said, that there were multitudes that made mention of the name of the Lord, that professed it, and swore by it; which sometimes is put for the worship and service of God, Deuteronomy 10:20 and therefore it could not be so difficult a matter to find a man of integrity and uprightness among them; this is answered by allowing there were persons that did do so: but then it must be observed,

that surely they swear falsely; they abused the name of God, and were guilty of perjury: or the sense is, they were only nominal professors, hypocritical worshippers; in words professed to know God, but in works denied him; had a form of religion and godliness, but without the power of it.

And though they say, The {b} LORD liveth; surely they swear falsely.

(b) Though they pretend religion and holiness, yet all is but hypocrisy: for under this kind of swearing is contained the true religion.

5:2 Though - Though when they swear, they use the form of an oath, and say, the Lord liveth, or by the living God: yet it is neither in truth nor righteousness.

2. (Tit 1:16).

swear falsely-not a judicial oath; but their profession of the worship of Jehovah is insincere (Jer 5:7; Jer 4:2). The reformation under Josiah was merely superficial in the case of the majority.

5:1-9 None could be found who behaved as upright and godly men. But the Lord saw the true character of the people through all their disguises. The poor were ignorant, and therefore they were wicked. What can be expected but works of darkness, from people that know nothing of God and religion? There are God's poor, who, notwithstanding poverty, know the way of the Lord, walk in it, and do their duty; but these were willingly ignorant, and their ignorance would not be their excuse. The rich were insolent and haughty, and the abuse of God's favours made their sin worse.
