'Assembled' in the Bible

So David assembled all Israel together, from the Shihor of Egypt even to the entrance of Hamath, to bring the ark of God from Kiriath-jearim.

And David assembled all Israel at Jerusalem to bring up the ark of the Lord to its place which he had prepared for it.

Now David assembled at Jerusalem all the officials of Israel, the princes of the tribes, and the commanders of the divisions that served the king, and the commanders of thousands, and the commanders of hundreds, and the overseers of all the property and livestock belonging to the king and his sons, with the officials and the mighty men, even all the valiant men.
