'Becomes' in the Bible

Then the Lord said to Moses, "Tell Aaron, 'Take your staff and stretch out your hand over Egypt's waters -- over their rivers, over their canals, over their ponds, and over all their reservoirs -- so that it becomes blood.' There will be blood everywhere in the land of Egypt, even in wooden and stone containers."

For seven days the son who becomes priest in his place will put them on when he comes into the Tent of meeting to do the work of the holy place.
