וְאִ֗ישׁ אֲשֶׁ֨ר יִתֵּ֧ן שְׁכָבְתּ֛וֹ בִּבְהֵמָ֖ה מ֣וֹת יוּמָ֑ת וְאֶת־הַבְּהֵמָ֖ה תַּהֲרֹֽגוּ׃
And if a man lie with a beast, he shall surely be put to death; and ye shall slay the beast.
Leviticus
A man, if semen issues from him, he shall bathe his entire body in water and is impure until the evening.
