'Pray for' in the Bible

But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them that despitefully use you and persecute you:

Bless them that curse you, pray for them that despitefully use you.

I pray for them: I pray not for the world, but for them whom thou hast given me; for they are thine.

Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought; but the Spirit itself maketh intercession for us, with groanings which cannot be uttered.

Brethren, pray for us.

Finally, brethren, pray for us, that the word of the Lord may run and be glorified, even as among you:

Pray for us; for we trust we have a good conscience, desiring to behave ourselves well in all things.

There is a sin unto death: I do not say that he shall pray for that. All unrighteousness is sin: but there is a sin not unto death.
