“This is perfectly good English, although now archaic. It means, ‘he became exhausted,’ ‘tired out.’ (See Deut. 29:5; Heb. 8:13.)
“Lehi’s last act in mortality was to bless his posterity. And, let no one regard this as a mere formality. A father’s blessing by the power of the Priesthood is a draft on the unlimited resources of heaven, which our Eternal Father has obligated himself to honor” (Reynolds and Sjodahl, Commentary on the Book of Mormon, 1:261–62).
