“Yea, ye yourselves know, that these hands have ministered unto my necessities, and to them that were with me.”

“Know ye therefore that they which are of faith, the same are the children of Abraham.”

“For this cause, when I could no longer forbear, I sent to know your faith, lest by some means the tempter have tempted you, and our labour be in vain.”

“Knowing this first, that there shall come in the last days scoffers, walking after their own lusts,”
