But what I am doing, I will continue to do, so that I can cut off the opportunity from those who want an occasion [to receive financial support for themselves because of my example of receiving it]. They want to boast [that they are preaching] on the same terms as I do.

Philippians 3:2-3
Watch out for the "dogs!" [Note: "Dogs" were viewed with disgust by the ancient Jews (Deut. 23:18; II Kings 8:13; Rev. 22:15), so the term is used here derogatorily for Jewish Christians who were trying to impose on the church the requirements of the law of Moses].

Dear children, it is [now] the last hour [i.e., the final period of God's dealing with people on earth], and since you have heard that an antichrist [i.e., a person who is against Christ] is coming, even now [you should be aware that] many antichrists have [already] come.
