'Slave' in the Bible

Luxury is not fitting for a fool;Much less for a slave to rule over princes.

The rich rules over the poor,And the borrower becomes the lender’s slave.

A slave will not be instructed by words alone;For though he understands, there will be no response.

He who pampers his slave from childhoodWill in the end find him to be a son.

Do not slander a slave to his master,Or he will curse you and you will be found guilty.

Under a slave when he becomes king,And a fool when he is satisfied with food,
