מדרש אויף ירמיהו 38:16

"As haShem, the one who made this life for us, lives" (Jeremiah 38:16) — the scripture is missing the word "the one" because he had sworn once before and reneged, as it says, "And against the king Nebuchadnezzar, who had made him swear by God, he rebelled" (II Chronicles 36:13). And Ezekiel rebuked, "See if I don't, for My vow that he disrespected, and My covenant that he overturned" (Ezekiel 17:19), and Jeremiah said, "If 'as haShem lives' they say, then for falsehood they swear" (Jeremiah 5:2). Thus the scripture is lacking, and the oath is lacking, for it has a word that is written and not read.
