'Approaching' in the Bible

At their going into the tent of assembly and at their approaching the altar, they washed, as Yahweh had commanded Moses.

And I saw it approaching the ram and it was furious at it, and it struck the ram, and it broke its two horns, and {there was not strength in the ram to stand before him}, and he threw it down to the ground and trampled it, {and there was no one who could rescue the ram} from its power.
