'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 return answer to this people, who have spoken to me, saying, Make the yoke that thy father did put upon us lighter?

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