'Gather' in the Bible

And David said unto all the congregation of Israel, If it seem good unto you, and that it be of the LORD our God, let us send abroad unto our brethren every where, that are left in all the land of Israel, and with them also to the priests and Levites which are in their cities and suburbs, that they may gather themselves unto us:

And say ye, Save us, O God of our salvation, and gather us together, and deliver us from the heathen, that we may give thanks to thy holy name, and glory in thy praise.

And David commanded to gather together the strangers that were in the land of Israel; and he set masons to hew wrought stones to build the house of God.
