'Assembling' in the Bible

King Solomon and all the assembly of Israel who were assembling with him in the presence of the ark [were] sacrificing sheep and oxen that could not be counted nor numbered because of abundance.

Be ready, and prepare {yourselves}, you and all of your assembly, the assembling around you, and you must be for them as a guard.

And the satraps, the prefects, the governors and the advisors of the king [were] assembling, [and] they saw these men, that the fire had no power over their bodies, and the hair of their heads was not singed, and their garments were not harmed, and the smell of fire did not come from them.
