Luke 1:59 And it came to pass, that on the eighth day they came to circumcise the child; and they called him Zacharias, after the name of his father. Acts 7:8 And he gave him the covenant of circumcision: and so Abraham begat Isaac, and circumcised him the eighth day; and Isaac begat Jacob; and Jacob begat the twelve patriarchs. 2 Peter 2:5 And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly; Revelation 17:11 And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition. Revelation 21:20 The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst.
