Philippians 1:7 - Even as it is meet for me to think this of you all, because I have you in my heart; inasmuch as both in my bonds, and in the defence and confirmation G951 of the gospel, ye all are partakers of my grace.
Hebrews 6:16 - For men verily swear by the greater: and an oath for confirmation G951 is to them an end of all strife.
