Genesis 7:2 Halakhah

מִכֹּ֣ל ׀ הַבְּהֵמָ֣ה הַטְּהוֹרָ֗ה תִּֽקַּח־לְךָ֛ שִׁבְעָ֥ה שִׁבְעָ֖ה אִ֣ישׁ וְאִשְׁתּ֑וֹ וּמִן־הַבְּהֵמָ֡ה אֲ֠שֶׁר לֹ֣א טְהֹרָ֥ה הִ֛וא שְׁנַ֖יִם אִ֥ישׁ וְאִשְׁתּֽוֹ׃

Of every clean beast thou shalt take to thee seven and seven, each with his mate; and of the beasts that are not clean two [and two], each with his mate;
