'Whoever' in the Bible

Then the Lord said to Gideon, There are still more people than is necessary; take them down to the water so that I may put them to the test for you there; then whoever I say is to go with you will go, and whoever I say is not to go will not go.

Then whoever comes out from the door of my house, meeting me when I come back in peace from the children of Ammon, will be the Lord's and I will give him as a burned offering.

And the children of Israel said, Who is there among all the tribes of Israel, who did not come up to the Lord at the meeting of all Israel? For they had taken a great oath that whoever did not come up to Mizpah to the Lord was to be put to death.
