אַף־תָּ֭שִׁיב צ֣וּר חַרְבּ֑וֹ וְלֹ֥א הֲ֝קֵימֹת֗וֹ בַּמִּלְחָמָֽה׃
Yea, Thou turnest back the edge of his sword, And hast not made him to stand in the battle.
Rashi on Psalms
You even turned back the sharp edge of his sword You turned back and reversed the sharp edge of his sword, as (Josh. 5:2): “sharp (צרים) knives,” and likewise (Isa. 54:17): “Any weapon whetted (יוצר) against you.”
Rashi on Psalms
and You did not raise him up in battle And You did not hold him upright so that he should not fall.
