Joab said [to Abishai], “If the Arameans are too strong for me, then you shall help me; but if the Ammonites are too strong for you, I will come to help you.
Be courageous, and let us show ourselves courageous for the benefit of our people and the cities of our God. And may the Lord do what is good in His sight.”
but I have prayed [especially] for you [Peter], that your faith [and confidence in Me] may not fail; and you, once you have turned back again [to Me], strengthen and support your brothers [in the faith].”
Now we who are strong [in our convictions and faith] ought to [patiently] put up with the weaknesses of those who are not strong, and not just please ourselves.
