יָג֤וּרוּ ׀ יצפינו [יִצְפּ֗וֹנוּ] הֵ֭מָּה עֲקֵבַ֣י יִשְׁמֹ֑רוּ כַּ֝אֲשֶׁ֗ר קִוּ֥וּ נַפְשִֽׁי׃
They gather themselves together, they hide themselves, They mark my steps; According as they have waited for my soul.
Rashi on Psalms
They lodge, they hide They lurk and lodge in the place they hope I will go, and they watch my steps (traces in French, tracks, explained in Gen. 49:19, Song of Songs 1:8) to spy on me and to lead pursuers there. All this he would complain about the wicked of Israel: that they would lie in wait for him and out of fear of them he had fled to Achish.
Rashi on Psalms
when they hope for my life When they know [that I will pass] and hope for me, “He will go this way.”
