'Although' in the Bible

For this reason I shall always persist in reminding you of these things, although you know them and are stedfast believers in truth which you already possess.

And He did not spare the ancient world, although He preserved Noah, a herald of righteousness, with seven others, when He brought a deluge on the world of the ungodly.

And they promise them freedom, although they are themselves the slaves of what is corrupt. For a man is the slave of any one by whom he has been worsted in fight.
