Jeremiah 44:26

26 `Therefore, hear ye a word of Jehovah, all Judah who are dwelling in the land of Egypt: Lo, I -- I have sworn by My great name, said Jehovah, My name is no more proclaimed by the mouth of any man of Judah, saying, Live doth the Lord Jehovah -- in all the land of Egypt.

Jeremiah 44:26 Meaning and Commentary

Jeremiah 44:26

Therefore hear ye the word of the Lord, all Judah that dwell
in the land of Egypt (See Gill on Jeremiah 44:24); since you have made your vows, and will perform them, I will take an oath, and abide by it: behold, I have sworn by my great name, saith the Lord;
by his name Jehovah, which is incommunicable, and expressive of his eternity and immutability; or by himself, his name being himself, and than which he can swear by no greater, ( Hebrews 6:13 ) ; that my name shall no more be named in the mouth of any man of Judah
in all the land of Egypt, saying, the Lord God liveth:
this cannot be understood of the name of the Lord being called upon them, or of their being called by his name, and reckoned his people, which is the sense of Abarbinel; since this respects not a name by which they should be named, but which they should name; and intends their use of the divine name in an oath, of which this is a form, "the Lord God liveth": or as sure as the Lord lives, or by the living God, it is so and so; and especially as used in their vows to burn incense to the queen of heaven, they vowing by the living God that they would do so, which must be very abominable to him; and therefore he solemnly swears there should not be a Jew in all Egypt that should use it; the reason is, because everyone of them that did should be cut off, as follows:

Jeremiah 44:26 In-Context

24 And Jeremiah saith unto all the people, and unto all the women, `Hear ye a word of Jehovah, all Judah who [are] in the land of Egypt,
25 Thus spake Jehovah of Hosts, God of Israel, saying: Ye and your wives both speak with your mouth, and with your hands have fulfilled, saying: We certainly execute our vows that we have vowed, to make perfume to the queen of the heavens, and to pour out to her libations, ye do certainly establish your vows, and certainly execute your vows.
26 `Therefore, hear ye a word of Jehovah, all Judah who are dwelling in the land of Egypt: Lo, I -- I have sworn by My great name, said Jehovah, My name is no more proclaimed by the mouth of any man of Judah, saying, Live doth the Lord Jehovah -- in all the land of Egypt.
27 Lo, I am watching over them for evil, and not for good, and consumed have been all the men of Judah who [are] in the land of Egypt, by sword and by famine, till their consumption.
28 `And the escaped of the sword turn back out of the land of Egypt to the land of Judah, few in number, and known have all the remnant of Judah who are coming into the land of Egypt to sojourn there, whose word is established, Mine or theirs.
