'Base' in the Bible

Certain base fellows are gone out from the midst of you, and have drawn away the inhabitants of their city, saying, "Let us go and serve other gods," which you have not known;

Beware that there not be a base thought in your heart, saying, "The seventh year, the year of release, is at hand;" and your eye be evil against your poor brother, and you give him nothing; and he cry to Yahweh against you, and it be sin to you.
