וְהֵֽבֵאתָ֤ אֶת־הַבַּדִּים֙ בַּטַּבָּעֹ֔ת עַ֖ל צַלְעֹ֣ת הָאָרֹ֑ן לָשֵׂ֥את אֶת־הָאָרֹ֖ן בָּהֶֽם׃
And thou shalt put the staves into the rings on the sides of the ark, wherewith to bear the ark.
Targum Jonathan on Exodus
and thou shalt introduce the staves into the rings on the sides of the ark, that the ark may be carried upon them.
