John Gill Bible Commentary

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.
