'Peace' in the Bible

'Peace I leave to you; my peace I give to you, not according as the world doth give do I give to you; let not your heart be troubled, nor let it be afraid;

these things I have spoken to you, that in me ye may have peace, in the world ye shall have tribulation, but take courage -- I have overcome the world.'

It being, therefore, evening, on that day, the first of the sabbaths, and the doors having been shut where the disciples were assembled, through fear of the Jews, Jesus came and stood in the midst, and saith to them, 'Peace to you;'

Jesus, therefore, said to them again, 'Peace to you; according as the Father hath sent me, I also send you;'

And after eight days, again were his disciples within, and Thomas with them; Jesus cometh, the doors having been shut, and he stood in the midst, and said, 'Peace to you!'
