If thou do these things, shew thyself to the world. 5 For neither did his brethren believe in him. 6 Then Jesus said unto them, My time is not yet come: but your time is alway ready. 7 The world cannot hate you; but me it hateth, because I testify of it, that the works thereof are evil. 8 Go ye up unto this feast: I go not up yet unto this feast: for my time is not yet full come. 9 When he had said these words unto them, he abode still in Galilee. 10 But when his brethren were gone up, then went he also up unto the feast, not openly, but as it were in secret.
