תַּנְיָא, בֶּן נֹחַ שֶׁבָּא בִּיאָה אֲסוּרָה בְּהַעֲרָאָה חַיָּב, שֶׁנֶּאֱמַר וְדָבַק בְּאִשְׁתּוֹ וְלֹא בְּאֵשֶׁת חֲבֵרוֹ, וְדָבַק — דֶּבֶק כָּל שֶׁהוּא.
English: It was taught: A child of Noach who performs a forbidden act of intercourse with even the slightest penetration is liable, as it is said “and he shall cleave to his wife and not to his fellow’s wife,” and “davak” means any degree of cleaving.
