Leviticus 1:1 And the LORD called unto Moses, and spake unto him out of the tabernacle of the congregation, saying,

Exodus 25:22 And there I will meet with thee, and I will commune with thee from above the mercy seat, from between the two cherubims which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel.

Numbers 7:89 And when Moses was gone into the tabernacle of the congregation to speak with him, then he heard the voice of one speaking unto him from off the mercy seat that was upon the ark of testimony, from between the two cherubims: and he spake unto him.
