A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown  at sacred-texts.com
jer 43:2THE JEWS CARRY JEREMIAH AND BARUCH INTO EGYPT. JEREMIAH FORETELLS BY A TYPE THE CONQUEST OF EGYPT BY NEBUCHADNEZZAR, AND THE FATE OF THE FUGITIVES. (Jer 43:1-13)
Azariah--the author of the project of going into Egypt; a very different man from the Azariah in Babylon (Dan 1:7; Dan 3:12-18).
proud--Pride is the parent of disobedience and contempt of God.
jer 43:3Baruch--He being the younger spake out the revelations which he received from Jeremiah more vehemently. From this cause, and from their knowing that he was in favor with the Chaldeans, arose their suspicion of him. Their perverse fickleness was astonishing. In the forty-second chapter they acknowledged the trustworthiness of Jeremiah, of which they had for so long so many proofs; yet here they accuse him of a lie. The mind of the unregenerate man is full of deceits.
jer 43:5remnant . . . returned from all nations-- (Jer 40:11-12).
jer 43:6the king's daughters--Zedekiah's (Jer 41:10).
jer 43:7Tahpanhes--(See on Jer 2:16); Daphne on the Tanitic branch of the Nile, near Pelusium. They naturally came to it first, being on the frontier of Egypt, towards Palestine.
jer 43:9stones--to be laid as the foundation beneath Nebuchadnezzar's throne (Jer 43:10).
brick-kiln--Bricks in that hot country are generally dried in the sun, not burned. The palace of Pharaoh was being built or repaired at this time; hence arose the mortar and brick-kiln at the entry. Of the same materials as that of which Pharaoh's house was built, the substructure of Nebuchadnezzar's throne should be constructed. By a visible symbol implying that the throne of the latter shall be raised on the downfall of the former. Egypt at that time contended with Babylon for the empire of the East.
jer 43:10my servant--God often makes one wicked man or nation a scourge to another (Eze 29:18-20).
royal pavilion--the rich tapestry (literally, "ornament") which hung round the throne from above.
jer 43:11such as are for death to death--that is, the deadly plague. Some he shall cause to die by the plague arising from insufficient or bad food; others, by the sword; others he shall lead captive, according as God shall order it (see on Jer 15:2).
jer 43:12houses of . . . gods--He shall not spare even the temple, such will be His fury. A reproof to the Jews that they betook themselves to Egypt, a land whose own safety depended on helpless idols.
burn . . . carry . . . captives--burn the Egyptian idols of wood, carry to Babylon those of gold and other metals.
array himself with the land, &c.-- Isa 49:18 has the same metaphor.
as a shepherd, &c.--He shall become master of Egypt as speedily and easily as a shepherd, about to pass on with his flock to another place, puts on his garment.
jer 43:13images--statues or obelisks.
Beth-shemesh--that is, "the house of the sun," in Hebrew; called by the Greeks "Heliopolis"; by the Egyptians, "On" (Gen 41:45); east of the Nile, and a few miles north of Memphis. Ephraim Syrus says, the statue rose to the height of sixty cubits; the base was ten cubits. Above there was a miter of a thousand pounds weight. Hieroglyphics are traced around the only obelisk remaining in the present day, sixty or seventy feet high. On the fifth year after the overthrow of Jerusalem, Nebuchadnezzar, leaving the siege of Tyre, undertook his expedition to Egypt [JOSEPHUS, Antiquities, 10.9,7]. The Egyptians, according to the Arabs, have a tradition that their land was devastated by Nebuchadnezzar in consequence of their king having received the Jews under his protection, and that it lay desolate forty years. But see on Eze 29:2; Eze 29:13.
shall he burn--Here the act is attributed to Nebuchadnezzar, the instrument, which in Jer 43:12 is attributed to God. If even the temples be not spared, much less private houses.
