'Do Good' in the Bible

Then said Jesus unto them, I will ask you one thing; Is it lawful on the sabbath days to do good, or to do evil? to save life, or to destroy it?

But I say unto you which hear, Love your enemies, do good to them which hate you,

And if ye do good to them which do good to you, what thank have ye? for sinners also do even the same.

But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil.
