“sinews.” The Hebrew word is giyd (#01517 גִּיד), and the part of the body this refers to is not exactly known. A few translations say “tendons” and some others say “ligaments,” but most say “sinews.” The word “sinew” refers to tough fibrous tissue that connects bone to bone or muscle to bone, and it seems that God is using the term in a general way here since the bones needed sinew of different types to be mobile when they came alive.
