'Beside' in the Bible

The priest is to put on his linen robe and linen undergarments. He is to remove the ashes of the burnt offering the fire has consumed on the altar, and place them beside the altar.

Moses spoke to Aaron and his remaining sons, Eleazar and Ithamar: “Take the grain offering that is left over from the fire offerings to the Lord, and eat it prepared without yeast beside the altar, because it is especially holy.
