'Heavy' in the Bible

Thy father made our yoke grievous; and now lighten thou the grievous servitude of thy father and his heavy yoke that he put upon us, and we will serve thee.

And the young men that had grown up with him spoke to him saying, Thus shalt thou say to this people that have spoken to thee saying, Thy father made our yoke heavy, and lighten thou it for us, thus shalt thou say to them: My little finger is thicker than my father's loins;

and whereas my father laid a heavy yoke upon you, I will add to your yoke: my father chastised you with whips, but I will chastise you with scorpions.

and he spoke to them according to the advice of the young men, saying, My father made your yoke heavy, but I will add to your yoke: my father chastised you with whips, but I will chastise you with scorpions.
