Targum for Exodus 37:1

וַיַּ֧עַשׂ בְּצַלְאֵ֛ל אֶת־הָאָרֹ֖ן עֲצֵ֣י שִׁטִּ֑ים אַמָּתַ֨יִם וָחֵ֜צִי אָרְכּ֗וֹ וְאַמָּ֤ה וָחֵ֙צִי֙ רָחְבּ֔וֹ וְאַמָּ֥ה וָחֵ֖צִי קֹמָתֽוֹ׃

And Bezalel made the ark of acacia-wood: two cubits and a half was the length of it, and a cubit and a half the breadth of it, and a cubit and a half the height of it.
