'Let Us' in the Bible

let us make, I pray thee, a little upper chamber of the wall, and we set for him there a bed, and a table, and a high seat, and a candlestick; and it hath been, in his coming in unto us, he doth turn aside thither.'

let us go, we pray thee, unto the Jordan, and we take thence each one beam, and we make for ourselves there a place to dwell there;' and he saith, 'Go.'
