2 Corinthians 12:14

Behold the third time. The first visit was when he converted them; the second time he was ready to start, but postponed his visit for good reasons; the third occasion was at the time of his writing, and took place actually afterwards (S. Thomas and Lyranus).

For the children ought not to lay up for the parents. A euphemism. Earthly parents lay up treasure for their children; spiritual fathers, on the other hand, should be supported by their children, i.e., by the catechumens and the faithful. I am to you, says S. Paul, such a spiritual father, that I wish to be also an earthly one, and expend upon you myself and all that I have. He thus gently chides them, that they may see how great an Apostle he is, how high-minded, of how great charity, and be confounded for not returning his love, and for preferring the false apostles, who thought only of themselves and their own gain. Ver. 15. And I will very gladly spend and be spent for you. I will spend all my goods, and then gladly give for you my blood, my spirit, my life (Anselm).
