'Let Us' in the Bible

they approached Zerubbabel and the leaders of the families and said to them, “Let us build with you, for we also worship your God and have been sacrificing to Him since the time King Esar-haddon of Assyria brought us here.”

Let us therefore make a covenant before our God to send away all the foreign wives and their children, according to the counsel of my lord and of those who tremble at the command of our God. Let it be done according to the law.
