Charles Ellicott Commentary Jeremiah 15:9

"She that hath borne seven languisheth; she hath given up the ghost; her sun is gone down while it was yet day; she hath been put to shame and confounded: and the residue of them will I deliver to the sword before their enemies, saith Jehovah." — Jeremiah 15:9 (ASV)

She that hath borne seven. —In the picture of the previous verse the glory of the mother was found in the valour of her son, here in the number of her children. “Seven,” as the perfect number, represented, as in 1 Samuel 2:5, Ruth 4:15, the typical completeness of the family.

Her sun is gone down while it was yet day. —The image of this eclipse of all joy and brightness may possibly have been suggested by the actual eclipse of the sun (total in Palestine), September 30, 610 BC, the year of the battle of Megiddo, just as the earthquake in the reign of Uzziah suggested much of the imagery of Isaiah and Amos (Isaiah 2:19; Amos 1:1–2; Amos 4:11; Zechariah 14:5). A like image meets us in Amos 8:9.
