וְעָשִׂ֥יתָ אֶת־הַמִּזְבֵּ֖חַ עֲצֵ֣י שִׁטִּ֑ים חָמֵשׁ֩ אַמּ֨וֹת אֹ֜רֶךְ וְחָמֵ֧שׁ אַמּ֣וֹת רֹ֗חַב רָב֤וּעַ יִהְיֶה֙ הַמִּזְבֵּ֔חַ וְשָׁלֹ֥שׁ אַמּ֖וֹת קֹמָתֽוֹ׃
Targum Jonathan on Exodus
And thou shalt make the Altar of woods of sitta; five cubits the length, and five cubits the breadth: square shall be the altar, and its height three cubits.
