'Base' in the Bible

The sons of Eli [Hophni and Phinehas] were worthless (dishonorable, unprincipled) men; they did not know [nor respect] the Lord

Then all the wicked and worthless men among those who went with David said, “Because they did not go with us, we will give them none of the spoil that we have recovered, except that each man may take his wife and children away and leave.”
