'Gather' in the Bible

Abner said to David, “Let me arise and go and gather all Israel to my lord the king, that they may make a covenant with you, and that you may be king over all that your soul desires.” So David sent Abner away, and he went in peace.

Now therefore, gather the rest of the people together and camp against the city and capture it, or I will capture the city myself and it will be named after me.”
