Leviticus 1:9

וְקִרְבּ֥וֹ וּכְרָעָ֖יו יִרְחַ֣ץ בַּמָּ֑יִם וְהִקְטִ֨יר הַכֹּהֵ֤ן אֶת־הַכֹּל֙ הַמִּזְבֵּ֔חָה עֹלָ֛ה אִשֵּׁ֥ה רֵֽיחַ־נִיח֖וֹחַ לַֽיהוָֽה׃ ס

τὰ δὲ ία αὐτοῦ καὶ τοὺς πόδας πλυνοῦσιν ὕδατι· καὶ ἐπιθήσουσιν οἱ τὰ πάντα ἐπὶ τὸ θυσιαστήριον· κάρπωμά ἐστιν, θυσία, ὀσμὴ εὐωδίας τῷ κυρίῳ.

Y lavará con agua sus intestinos y sus piernas: y el sacerdote hará arder todo sobre el altar: holocausto es, ofrenda encendida de olor suave á Jehová.

The entrails and legs must be washed with water, and the priest shall burn all of it on the altar as a burnt offering, an offering made by fire, a pleasing aroma to the LORD.
