'Assemble' in the Bible

So now, assemble the rest of the men, and camp against the city and capture it, or I will take the city myself, and it will be named after me.”

Now the king said to Amasa [the commander of his army], “Summon the [fighting] men of Judah to me within three days, and be present here yourself.”

So Amasa went to summon [the fighting men of] Judah, but he delayed longer than the time which David had set for him.
