מָֽגִנִּ֥י עַל־אֱלֹהִ֑ים מ֝וֹשִׁ֗יעַ יִשְׁרֵי־לֵֽב׃
Мой щит с Богом, Который спасает праведных сердцем.
Radak
My shield is upon God: – He might have said, My shield is God. What, then, is the significance of על, upon? Only that my reliance and stay is God, who will be my shield, for He is A deliverer of the upright of heart.
