Jeremiah 42:5
Then they said to Jeremiah, The LORD be a true and faithful witness between us, if we do not even according to all things for the which the LORD thy God shall send thee to us.
Then they said to Jeremiah, the Lord be a true and faithful witness between us,.... Which is the form of an oath; a solemn appeal to God, as a witness to what they were about to say, and to the sincerity of their hearts in it; who is true to his word, and faithful to his promises and threatenings; and who bears a true and faithful testimony, and will do what is just and right; and yet these people never intended to perform what they promised; which is a most shocking piece of atheism in a professing people; and who, at this very time, could not but observe the judgments of God upon their nation, city, and temple:
if we do not even according to all things for the which the LORD thy God shall send thee to us; they promise to do everything the Lord should signify by the prophet as his will; and, if they did not, wish the severest judgments of God might fall upon them.
