Numbers 35:17

וְאִ֡ם בְּאֶ֣בֶן יָד֩ אֲשֶׁר־יָמ֨וּת בָּ֥הּ הִכָּ֛הוּ וַיָּמֹ֖ת רֹצֵ֣חַֽ ה֑וּא מ֥וֹת יוּמַ֖ת הָרֹצֵֽחַ׃

ἐὰν δὲ ἐν λίθω ἐκ χειρὸς ἐν ᾧ ἀποθανεῖται ἐν αὐτῷ πατάξῃ αὐτόν, καὶ ἀποθάνῃ, φονευτής ἐστιν· θανάτῳ θανατούσθω ὁ φονευτής.

Y si con piedra de mano, de que pueda morir, lo hiriere, y muriere, homicida es; el homicida morirá.

Or if anyone has in his hand a stone of deadly size, and he strikes and kills another, he is a murderer; the murderer must surely be put to death.
