A.T. Robertson Commentary Hebrews 11:12

"wherefore also there sprang of one, and him as good as dead, [so many] as the stars of heaven in multitude, and as the sand, which is by the sea-shore, innumerable." — Hebrews 11:12 (ASV)

And that as good as dead (κα ταυτα νενεκρωμενου). Accusative of general reference (ταυτα), sometimes singular as in 1 Corinthians 6:8. The perfect passive participle from νεκροω, late verb to make dead, to treat as dead (Romans 4:19), here by hyperbole.

By the sea shore (παρα το χειλος της θαλασσης). "Along the lip of the sea" , χειλος here alone in this sense in the N.T.

Innumerable (αναριθμητος). Old compound verbal adjective (alpha privative and αριθμεω, to number), here alone in N.T.
