That made us this soul - This very unusual addition to the formula of an oath 1 Samuel 20:3 was intended to strengthen it. By acknowledging that his soul was God's workmanship Zedekiah also implied his belief in God's power over it.

As the Lord liveth, that made us this soul - He is the living God, and he is the Author of that life which each of us possesses; and as sure as he lives, and we live by him, I will not put thee to death, nor give thee into the hands of those men who seek thy life. A very solemn oath; and the first instance on record of the profane custom of swearing by the soul.

So Zedekiah the king swore secretly unto Jeremiah,.... The king not only gave the prophet his word, but also annexed to it his oath, that his life should be in no danger, either from him or his princes; this oath was made secretly, both for the honour of the king, he swearing to a subject, and that it might not be known by the princes, and for fear of them:

saying, as the Lord liveth, that made us this soul; or "these souls", as the Targum: here a superfluous word, is used; which, as the Jews observe, is one of the eight words which are written, but not read: he swears by the living God, by whom only men should swear, whenever it is necessary; this is the proper form of an oath; the appeal is to be made to the eternal God, that knows all things, the Father of spirits, the Maker of souls, and giver of the lives of all men, and who can take them away when he pleases. The sense is, may the living God, who has made my soul and yours, and given life to us both, may he take away my soul, my life, from me, if ever I make any attempt upon yours;

I will not put thee to death, neither will I give thee into the hand of those that seek thy life; he not only promises and swears to it, that he would not take awake his life with his own hands, or give orders to take it away; but he would not deliver him into the hands of his princes, who he knew were implacable enemies, and sought all opportunities and advantages against him; but then he makes no promise that he will take any counsel or advice that should be given him; as to this, he would lay himself under no obligation to observe, resolving to take his own way; if he liked it, to follow it; if not, to reject it; he would not be bound by it.

So Zedekiah the king sware secretly unto Jeremiah, saying, As the LORD liveth, that made us this soul, I will not put thee to death, neither will I give thee into the hand of these men that seek thy life.

16. Lord . made us this soul-(Isa 57:16). Implying, "may my life (soul) be forfeited if I deceive thee" [Calvin].

38:14-28 Jeremiah was not forward to repeat the warnings, which seemed only to endanger his own life, and to add to the king's guilt, but asked whether he feared to do the will of God. The less men fear God, the more they fear men; often they dare not act according to their own judgments and consciences.
