'Heavy' 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 the young men that were grown up with him spake unto him, saying, Thus shalt thou say unto the 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 is thicker than my father's loins.

And now whereas my father did lade you with a heavy yoke, I will add to your yoke: my father chastised you with whips, but I will chastise you with scorpions.

and spake to them after the counsel of the young men, saying, My father made your yoke heavy, but I will add thereto: my father chastised you with whips, but I will chastise you with scorpions.
