'Let Us' in the Bible

And David said to all the congregation of Israel, If it seem good to you, and it be of Jehovah our God, let us send abroad to our brethren everywhere, that are left in all the lands of Israel, and with them to the priests and Levites in their cities and suburbs, that they may gather themselves to us;

and let us bring again the ark of our God to us; for we inquired not of it in the days of Saul.

Be strong, and let us shew ourselves valiant for our people, and for the cities of our God; and Jehovah will do what is good in his sight.
