'Abandoning' in the Bible

Abandoning the commandment of God, you hold fast to the tradition of men."

and likewise also the males, abandoning the natural relations with the female, were inflamed in their desire toward one another, males with males committing the shameless deed, and receiving in themselves the penalty that was necessary for their error.

not abandoning {our meeting together}, as [is] the habit of some, but encouraging [each other], and by so much more as you see the day drawing near.
