▼ The skin and flesh form the exterior of the body and so the image of “clothing” is appropriate. Once again the verb is the prefixed conjugation, expressing what God did.

▼ This verb is found only here (related nouns are common) and in the parallel passage of Ps 139:13. The word סָכַךְ (sakhakh), here a Poel prefixed conjugation (preterite), means “to knit together.” The implied comparison is that the bones and sinews form the tapestry of the person (compare other images of weaving the life).
