the loins are sometimes put for strength, as in Plautus ; and the sense is much the same with what follows;and strengtheneth her arms; does all she finds to do with all her might and main, as the church does; not in her own strength, but in the strength of Christ; to whom she seeks for it, and in whose strength she goes forth about her business; by whom the arms of her hands are made strong, even by the mighty God of Jacob; and because she thus applies to him for it, she is said to do it herself, Ge 49:24; here she plays the man, and acts the manly part, 1Co 16:13.
