The remnant of Judah refers to the survivors of the southern kingdom who endured severe trials and judgment, reduced to a small fraction of the whole, often likened to a tithe. After Assyrian and Babylonian invasions, Jerusalem fell, and most were killed or exiled, with a pitiful few remaining under Governor Gedeliah before fleeing to Egypt. Returns under Persian rule saw about 50,000 resettle, but the remnant quickly reverted to ancestral sins, facing rebukes from prophets like Haggai and Malachi. Despite military struggles, their survival hinges on spiritual condition, not strength, with God preserving a remnant through Jacob's Trouble for those who repent.
