Hebrews 11:11-12 Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised. Therefore sprang there even of one, and him as good as dead, so many as the stars of the sky in multitude, and as the sand which is by the sea shore innumerable. 

‘Sara’ – faith’s reckoning: Received strength to conceive seed. Was delivered of a child when past age (11:11; Gen. 17:17, 19; 21:1-8). She reckoned or counted God to be true to His word (11:11; cp. Rom. 4:19). She was as good as dead as far as having children was concerned (11:12). Innumerable seed came from her by God’s power through faith (11:11-12).

‘Received strength’ – Received here; given from above. Sara was 90 years old when she fell pregnant with Isaac.
