Rashi on Exodus 1:21/רש"י על שמות א׳:כ״א

1ויעש להם בתים HE MADE THEM HOUSES — houses (dynasties) of the priesthood and the Levites and of royalty which are all termed בתים, “houses”, as it is said, (1 Kings 9:1) “and Solomon built the house of the Lord and the house of the king”: “the house of the Lord” i. e. a dynasty of priests and Levites — from Jochebed (Shifrah); and “the house of the king”, i. e. a royal dynasty — from Miriam (Puah), just as it is stated in Treatise Sotah 11b.
