תַּ֭מְשִׁילֵהוּ בְּמַעֲשֵׂ֣י יָדֶ֑יךָ כֹּ֝ל שַׁ֣תָּה תַֽחַת־רַגְלָֽיו׃
Thou hast made him to have dominion over the works of Thy hands; Thou hast put all things under His feet:
Radak on Psalms
Thou makest him to have dominion over the works of Thy hands: – i.e. the inferior beings. Or the meaning of the expression may include the higher ones also; and the dominion then consists in his knowing by his understanding the movement of the spheres and the stars.
Radak on Psalms
Thou hast put all things under his feet: – The lower (beings) are all under him, as it says (Gen. 9:2): "And the fear of you and the dread of you shall be upon every beast of the earth and upon every fowl of the air.'"
