אַשְׁרֵ֣י אָ֭דָם עֽוֹז־ל֥וֹ בָ֑ךְ מְ֝סִלּ֗וֹת בִּלְבָבָֽם׃
Happy is the man whose strength is in Thee; in whose heart are the highways.
Rashi on Psalms
who has strength in You Who has made You the strength of his trust.
Rashi on Psalms
in whose heart are the highways Who thinks in his heart the paving of his ways, to straighten his way.
