Gevurot 21:24-26

Orthodox Jewish Bible

²⁴ "Go! Take these for hitkaddeshut (purification) and purify yourself with them and pay expenses for them, that they may cut their hair; then all shall have da’as that there is no emes to the rumor; then it shall be clear that you yourself are in agreement and frum regarding the darkhei haTorah and that you are charedi and shomer mitzvot, in the ranks of those who practice Orthodox Judaism." [BAMIDBAR 6:1-21, Mishnah tractate Nazir]

²⁵ “And concerning the Goyim coming to [Orthodox Jewish] emunah, we have sent an iggeret with our decision that they avoid what is offered to elilim and dahm and what is strangled and zenut."

²⁶ Then Rav Sha’ul took the anashim on the following day, and he went with them for hitkaddeshut (purification) and was entering the Beis Hamikdash, giving notice of the completion of the yamim of the tohorah until was offered for each one of them the korban. [BAMIDBAR 6:13 20]
