David and his men went against the Jebusites, who taunted that even the blind and lame could repel him. The text then states that David took the stronghold of Zion, which became the city of David. See 2 Samuel 5:6–7.
In 2 Samuel 5:6–7, David and his men march against Jerusalem, held by the Jebusites. The Jebusites mock him, claiming he will never enter unless he first removes “the blind and the lame,” a taunt meant to signal the city’s security and David’s inability. These verses sit early in the narrative of David’s reign, immediately after he has been established as king over all Israel (5:1–5). The story moves from David’s new status to an immediate military and political action: taking a key city.
These verses present a sharp contrast between what the Jebusites say and what actually happens. They speak with confidence that David will not get in, and they use the phrase “the blind and the lame” to mock him or the attempt itself. The narrator then directly states what they were thinking: David cannot enter. The next line reverses that expectation.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with 2 Samuel 5:6-7, then read the surrounding section so the answer stays connected to the passage's flow.
6The king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spoke to David, saying, Except you take away the blind and the lame, you shall not come in here; thinking, David can`t come in here.
7Nevertheless David took the stronghold of Zion; the same is the city of David.
