'Beside' in the Bible

The priest is to clothe himself with a linen robe and undergarments. Then he is to take the ashes of the burnt offering on the altar that had been consumed by the fire and set them beside the altar.

Then Moses told Aaron and his sons Eleazar and Ithamar, "Take the leftovers from the grain offering and the offerings made by fire and eat the unleavened bread beside the altar, because it is most holy to the LORD.
