gid denotes bodily connective cords and, figuratively, an unyielding neck.

The term most often denotes bodily connective cords in descriptions of formed or living bodies; in Isaiah 48:4 it is used figuratively of a neck characterized as iron.

1. Bodily connective cords · dominant

   Plural noun forms occur in bodily descriptions: in Ezekiel 37:6 and Ezekiel 37:8 the APB renders sinews appearing with flesh and skin, while in Job 10:11 it renders a body woven together with bones and sinews. In Job 40:17, the plural construct form is linked to the thighs, which the APB says “intertwine.”

2. Figurative iron-like neck · rare

   In Isaiah 48:4, the singular construct form stands in the expression “your neck is an iron sinew,” within a statement that the addressee is obstinate. The bodily term is thus applied to portray the neck as unyielding.

   Isaiah 48:4

In the Anselm Project Bible: The APB uses “sinews” in the bodily clauses of Ezekiel 37:6, Ezekiel 37:8, Job 10:11, and Job 40:17, and “iron sinew” for the neck in Isaiah 48:4. These are presentations of the translated verses rather than definitions.
