'Assembled' in the Bible

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

And he assembled together all the leaders of Israel with the priests and Levites.

David assembled at Jerusalem all the leaders (officials) of Israel, the leaders 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 of the king and his sons, with the palace officers and the mighty men, and all the brave warriors.
