Talmud for Tamid 4:1
לֹא הָיוּ כוֹפְתִין אֶת הַטָּלֶה, אֶלָּא מְעַקְּדִין אוֹתוֹ. מִי שֶׁזָּכוּ בָאֵבָרִים, אוֹחֲזִים בּוֹ. וְכָךְ הָיְתָה עֲקֵדָתוֹ, רֹאשׁוֹ לַדָּרוֹם וּפָנָיו לַמַּעֲרָב. הַשּׁוֹחֵט, עוֹמֵד בַּמִּזְרָח וּפָנָיו לַמַּעֲרָב. שֶׁל שַׁחַר הָיָה נִשְׁחָט עַל קֶרֶן צְפוֹנִית מַעֲרָבִית, עַל טַבַּעַת שְׁנִיָּה. שֶׁל בֵּין הָעַרְבַּיִם הָיָה נִשְׁחָט עַל קֶרֶן מִזְרָחִית צְפוֹנִית, עַל טַבַּעַת שְׁנִיָּה. שָׁחַט הַשּׁוֹחֵט, וְקִבֵּל הַמְקַבֵּל. בָּא לוֹ לְקֶרֶן מִזְרָחִית צְפוֹנִית, וְנוֹתֵן מִזְרָחָה צָפוֹנָה. מַעֲרָבִית דְּרוֹמִית, וְנוֹתֵן מַעֲרָבָה דָרוֹמָה. שְׁיָרֵי הַדָּם הָיָה שׁוֹפֵךְ עַל יְסוֹד דְּרוֹמִית:
They would not tie the lamb up [for slaughtering, as was normally done], but would bind it [right forelimb to right hind limb and left forelimb to left hind limb]. The ones who won [the right] to [carry] the limbs would hold it [as it was being slaughtered]. This is how they would bind it: its head would face south and its face turned [to face]to the west. The one slaughtering it stood to the east [of the lamb] with his face to the west. [The <i>Tamid</i> offering] of the morning was slaughtered on the north western corner [of the altar], on the second ring. The [<i>Tamid</i> offering] of the evening was slaughtered on the north eastern corner on the second ring. The slaughterer would slaughter and the one who [was designated] to receive [the blood] would receive it and go to the north eastern corner [of the altar] and tossed it to the east and north. [Then he went to] the south western [corner] and tossed it to the west and south. The rest of the blood was poured on the southern base [of the altar].
