הוֹרֵ֣נִי יְ֭הוָה דֶּ֥רֶךְ חֻקֶּ֗יךָ וְאֶצְּרֶ֥נָּה עֵֽקֶב׃
HE. Teach me, O LORD, the way of Thy statutes; And I will keep it at every step.
Rashi on Psalms
and I shall keep it at every step Heb. עקב. I shall keep it in all its paths and the steps of its paths, an expression of “heels” (עקבים), traces in French, footsteps.
