'Better' in the Bible

And Jehovah shall requite the blood which he shed upon his own head, because he fell upon two men more righteous and better than he, and slew them with the sword, without my father David's knowledge: Abner the son of Ner, captain of the host of Israel, and Amasa the son of Jether, captain of the host of Judah.

And he himself went a day's journey into the wilderness, and came and sat down under a certain broom-bush, and requested for himself that he might die; and said, It is enough: now, Jehovah, take my life; for I am not better than my fathers.

And Ahab spoke to Naboth saying, Give me thy vineyard, that I may have it for a garden of herbs, for it is near, by the side of my house; and I will give thee for it a better vineyard than it; if it seem good to thee, I will give thee its value in money.
