'Themselves' in the Bible

"How long, you simple ones, will you love simplicity? How long will mockers delight themselves in mockery, and fools hate knowledge?

Don't be among ones drinking too much wine, or those who gorge themselves on meat:

When the righteous triumph, there is great glory; but when the wicked rise, men hide themselves.

When the wicked rise, men hide themselves; but when they perish, the righteous thrive.
