'Although' in the Bible

who, although He existed in the form of God, did not regard equality with God a thing to be grasped,

although I once also had confidence in the flesh. If anyone else thinks he has grounds for confidence in the flesh, I have more:

But I rejoice with a deep and holy joy that now at length you have revived your thoughtfulness for my welfare. Indeed you have always been thoughtful for me, although opportunity failed you.
