'Conception' in the Bible

Unto the woman he said, I will greatly multiply thy pain and thy conception; in pain thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.

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

As for Ephraim, their glory shall fly away like a bird: there shall be no birth, and none with child, and no conception.
