'Let Us' in the Bible

and the Philistines call for priests and for diviners, saying, 'What do we do to the ark of Jehovah? let us know wherewith we send it to its place?'

And the elders of Jabesh say to him, 'Let us alone seven days, and we send messengers into all the border of Israel: and if there is none saving us -- then we have come out unto thee.'

And Saul saith, 'Let us go down after the Philistines by night, and we prey upon them till the light of the morning, and leave not a man of them.' And they say, 'All that is good in thine eyes do.' And the priest saith, 'Let us draw near hither unto God.'
