'Let Us' in the Bible

they approached Zerubbabel and the heads of fathers’ households, and said to them, “Let us build with you, for we, like you, seek your God; and we have been sacrificing to Him since the days of Esarhaddon king of Assyria, who brought us up here.”

So now let us make a covenant with our God to put away all the wives and their children, according to the counsel of my lord and of those who tremble at the commandment of our God; and let it be done according to the law.
