Comentario citado sobre Génesis 5:9

ויספר אל אביו ואל אחיו AND HE TOLD IT TO HIS FATHER AND TO HIS BRETHREN — After he had related it to his brothers (see 5:9) he again related it to his father in their presence.

וילדו AND THEY BROUGHT FORTH — Explain it as the Targum takes it: “and they were relieved” — their channels were opened (cf. 5:9) and they brought forth their secretions — and this is לידה “bringing forth”, as far as they are concerned.
