'Lighter' in the Bible

Thy father made our yoke grievous: now therefore make thou the grievous service of thy father, and his heavy yoke which he put upon us, lighter, and we will serve thee.

And he said unto them, What counsel give ye that we may answer this people, who have spoken to me, saying, Make the yoke which thy father did put upon us lighter?

And the young men that were grown up with him spake unto him, saying, Thus shalt thou speak unto this people that spake unto thee, saying, Thy father made our yoke heavy, but make thou it lighter unto us; thus shalt thou say unto them, My little finger shall be thicker than my father's loins.

And the young men that were brought up with him spake unto him, saying, Thus shalt thou answer the people that spake unto thee, saying, Thy father made our yoke heavy, but make thou it somewhat lighter for us; thus shalt thou say unto them, My little finger shall be thicker than my father's loins.

Surely men of low degree are vanity, and men of high degree are a lie: to be laid in the balance, they are altogether lighter than vanity.
