וְ֭לִבָּם לֹא־נָכ֣וֹן עִמּ֑וֹ וְלֹ֥א נֶ֝אֶמְנ֗וּ בִּבְרִיתֽוֹ׃
Потому что их сердце не было твердо с Ним, и они не были верны в Его завете.
Duties of the Heart
On the other hand, one whose inner [being] is not consistent with his outer [life] is condemned by Scripture, as written: "his heart was not whole with the L-ord, his G-d" (Kings 11:4), and "but they flatter Him with their mouths and lied with their tongues. For their heart was not steadfast with Him" (Ps. 78:36).
