In speaking to his people who are in bondage, Limhi apparently paraphrases the words of the Lord concerning the actions which might free them from bondage:
But if ye will turn to the Lord with full purpose of heart, and put your trust in him, and serve him with all diligence of mind, if ye do this, he will, according to his own pleasure, deliver you out of bondage. (Mosiah 7:33)
In a cultural note, Blair Van Dyke writes that the word heart here could be a translation of the Hebrew word leb. Figuratively, leb encompasses all dimensions of human existence. It signifies intellect, wisdom, vitality, emotion, conscience--indeed the very essence of a person lies within the leb (see Psalm 22:15; 27:3; 33:21; 45:2). [Blair G. Van Dyke, "Profiles of a Covenant People," in Covenants Prophecies and Hymns of the Old Testament, p. 49, n. 9]
