'Conception' in the Bible

And Boaz took Ruth, and she became his wife; and he went in unto her, and Jehovah gave her conception, and she bore a son.

As for Ephraim, their glory shall fly away as a bird, no birth, no pregnancy, no conception!

By faith also Sarah herself received strength for the conception of seed, and that beyond a seasonable age; since she counted him faithful who promised.
