Tanakh for Yevamot 6:1

הַבָּא עַל יְבִמְתּוֹ, בֵּין בְּשׁוֹגֵג, בֵּין בְּמֵזִיד, בֵּין בְּאֹנֶס, בֵּין בְּרָצוֹן, אֲפִלּוּ הוּא שׁוֹגֵג וְהִיא מְזִידָה, הוּא מֵזִיד וְהִיא שׁוֹגֶגֶת, הוּא אָנוּס וְהִיא לֹא אֲנוּסָה, הִיא אֲנוּסָה וְהוּא לֹא אָנוּס, אֶחָד הַמְעָרֶה וְאֶחָד הַגּוֹמֵר, קָנָה, וְלֹא חָלַק בֵּין בִּיאָה לְבִיאָה:

If one cohabits with his yevamah, (he acquires her) — whether unwittingly [thinking her to be another woman], wilfully, [wantonly, and not for the sake of the mitzvah], constrainedly, or wittingly. Even if he is unwitting and she wilful; he, wilful and she, unwitting; he, constrained and she, unconstrained; she, constrained and he, unconstrained. [Not only (is she acquired) when she intends the mitzvah; but even where both do not intend the mitzvah, as when he intends a different woman and she intends a wanton act, he acquires her, it being written (Deuteronomy 25:5): "Her yavom shall come upon her" — in any instance.] Whether he is ma'areh [If he does not consummate his intercourse, but just inserts the corona alone (The touching of the corona without entry is called neshikah, "kissing"], or consummates the act, he acquires her. [And he inherits (his dead brother) and he must give her a get if he wishes to send her away.] And no distinction was made between one type of intercourse and another [whether normal or non-normal (anal) intercourse, it being written (Leviticus 18:22): "the lyings" of a woman, Scripture positing two "lyings" for a woman.]

You shall not lie with a male [conjugally] as one lies with a woman; it is an abomination.

A man who will lie [conjugally] with [another] man, in the same manner as with a woman; they both have committed an abominable act, they shall surely be put to death, their blood is on them.

Deuteronomy

If brothers reside together, and one of them dies having no son, let the wife of the dead man not marry outside [the family] to a strange man; her brother-in-law will consummate with her thus marrying her to be his wife, and perform levirate marriage with her.
