'Prolong' in the Bible

Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.

Against whom do ye sport yourselves? Against whom enlarge ye the mouth? Prolong ye the tongue? Are not ye children of transgression? a false seed?
