'Assembled' in the Bible

So David assembled all of Israel from the Shihor River of Egypt to Lebo-hamath in order to bring the Ark of God from Kiriath-jearim.

David assembled all of Israel in Jerusalem to bring up the ark of the LORD to its proper place that he had prepared for it.

David also assembled the descendants of Aaron, who were descendants of Levi,

When David learned this, he mustered all of Israel, crossed the Jordan, approached the Arameans, and drew up his forces against them. After David had assembled in battle array against the Arameans, the Arameans attacked him.
