World English Bible

²⁰ “You shall command the children of Israel, that they bring to you pure olive oil beaten for the light, to cause a lamp to burn continually. ²¹ In the Tent of Meeting, outside the veil which is before the covenant, Aaron and his sons shall keep it in order from evening to morning before Yahweh: it shall be a statute forever throughout their generations on the behalf of the children of Israel.
