'Arise' in the Bible

Moses my servant is dead; now therefore arise, go over this Jordan, thou, and all this people, unto the land which I do give to them, even to the children of Israel.

And the LORD said unto Joshua, Fear not, neither be thou dismayed: take all the people of war with thee, and arise, go up to Ai: see, I have given into thy hand the king of Ai, and his people, and his city, and his land:

Provide for yourselves three men from each tribe that I may send them, and that they may arise and walk through the land and write a description of it according to their inheritance; then they shall return to me.
