'Rejoice' in the Bible

Who are glad -- unto joy, They rejoice when they find a grave.

They lift themselves up at timbrel and harp, And rejoice at the sound of an organ.

See do the righteous and they rejoice, And the innocent mocketh at them,

If I rejoice because great is my wealth, And because abundance hath my hand found,

If I rejoice at the ruin of my hater, And stirred up myself when evil found him,
