דִּמְיֹנ֗וֹ כְּ֭אַרְיֵה יִכְס֣וֹף לִטְר֑וֹף וְ֝כִכְפִ֗יר יֹשֵׁ֥ב בְּמִסְתָּרִֽים׃
He is like a lion that is eager to tear in pieces, And like a young lion lurking in secret places.
Rashi on Psalms
which yearns Heb. יכסף, yearns, as (in Gen. 31:30): “for you yearned (נכסף נכספתי).”
Radak on Psalms
He is like a lion that is greedy of his prey, As it were a young lion lurking in secret places: – He is like, singular, of Saul. He says, as he said of him in the Psalm Concerning the words of Cush, a Benjamite (7:3): "Lest he tear my soul like a lion."
