11 And Hashem spoke unto Moshe, saying,
12 And I, hinei, I have taken the Levi'im from among the Bnei Yisroel instead of all the bechor that openeth the womb among the Bnei Yisroel; therefore the Levi'im shall be Mine;
13 Because all the bechor are Mine; for on the yom that I struck down all the bechor in Eretz Mitzrayim I set apart as kodesh unto Me all the bechor in Yisroel, both man and beast: Mine shall they be: I am Hashem.
14 And Hashem spoke unto Moshe in the midbar of Sinai, saying,
15 Count the Bnei Levi by the bais of their avot, by their mishpekhot; every zachar from a month old and upward shalt thou number them.
16 And Moshe numbered them according to the command of Hashem, as he had been commanded.
17 And these were the Bnei Levi by their shmot: Gershon, Kehat, and Merari.
