'Weightier' in the Bible

"Alas for you, Scribes and Pharisees, hypocrites, for you pay the tithe on mint, dill, and cumin, while you have neglected the weightier requirements of the Law--just judgement, mercy, and faithful dealing. These things you ought to have done, and yet you ought not to have left the others undone.

"But the testimony which I have is weightier than that of John; for the work the Father has assigned to me for me to bring it to completion--the very work which I am doing--affords testimony concerning me that the Father has sent me.
