Genesis 3:21
19 By the sweat of your brow you will eat food until you return to the ground, for out of it you were taken; for you are dust, and to dust you will return.” 20 The man named his wife Eve, because she was the mother of all the living. 21 The Lord God made garments from skin for Adam and his wife, and clothed them. 22 And the Lord God said, “Now that the man has become like one of us, knowing good and evil, he must not be allowed to stretch out his hand and take also from the tree of life and eat, and live forever.”
Leviticus 16:4
3 “In this way Aaron is to enter into the sanctuary—with a young bull for a sin offering and a ram for a burnt offering. 4 He must put on a holy linen tunic, linen leggings are to cover his body, and he is to wrap himself with a linen sash and wrap his head with a linen turban. They are holy garments, so he must bathe his body in water and put them on. 5 He must also take two male goats from the congregation of the Israelites for a sin offering and one ram for a burnt offering.
Notes and References
"... “to clothe [in] a tunic” (Genesis 3:21; Leviticus 16:4). The noun תנתכ is uncommon, appearing only twenty-eight times in the Old Testament. While תנתכ, meaning “tunic,” “shirt-like tunic,” or “garment, coat, robe,” can be used in a general sense (e.g., Genesis 37:3), it often specifically denotes priestly clothing (e.g., Exodus 29:5; Ezra 2:69). The combination of תנתכ with the verb שׁבל occurs only seven times in the Pentateuch (Genesis 3:21; Exodus 29:5, 8; 40:14; Leviticus 8:7, 13; 16:4) and thrice more in the remainder of the Old Testament (2 Samuel 13:18; Song of Songs 5:3; Isaiah 22:21). Genesis 3:21 recounts the clothing of Adam and his wife in “tunics of skin” (רוע תונתכ) by YHWH God. The remaining Pentateuch occurrences of the word pair are used explicitly to denote dressing in priestly garb ..."
