וְאִ֗ישׁ אֲשֶׁ֤ר יִשְׁכַּב֙ אֶת־כַּלָּת֔וֹ מ֥וֹת יוּמְת֖וּ שְׁנֵיהֶ֑ם תֶּ֥בֶל עָשׂ֖וּ דְּמֵיהֶ֥ם בָּֽם׃
At ang lalaking sisiping sa kanyang manugang na babae, silang dalawa ay tiyak na papatayin; gumawa sila ng kasuklam-suklam na paghahalo, ang kanilang dugo ay nasa kanila.
Rashi
תבל עשו THEY HAVE WROUGHT תבל — i. e. they have done a shameful deed. Another interpretation is that תבל is connected with בלל to "intermingle" and signifies that they mingle (בּלל) the seed of the father with the seed of the son.
Siftei Chakhamim
They mix. According to the first interpretation, the root [of the word] is תבל, which has [two meanings], an expression of despising, or a term referring to all the lands [of the world]. According to the second interpretation, its root is בלל.
