וְעָשִׂ֥יתָ אֶת־הַקְּרָשִׁ֖ים לַמִּשְׁכָּ֑ן עֲצֵ֥י שִׁטִּ֖ים עֹמְדִֽים׃
And thou shalt make the boards for the tabernacle of acacia-wood, standing up.
Targum Jonathan on Exodus
And thou shalt make the boards of the tabernacle of sittin woods; they shall stand up, after the manner of their plantation.
