Philippians 1:15

“Some, indeed, preach Christ, etc.] That is, some of them, as the Arabic version reads; some of the brethren, that were only so in profession; wherefore these could not be the unbelieving Jews, who preached the Messiah in general, but did not believe Jesus of Nazareth to be he, and opened the prophecies of the Old Testament relating to him, to the Gentiles; at which the apostle is by some thought to rejoice; inasmuch as this might be a means of giving light to them that were without any knowledge of the Messiah, and of leading them into an inquiry concerning him, whereby they might come to know the true Messiah, and believe in him: for these men were brethren, were members of the church, and…”

“"Some indeed are preaching Christ even for envy, that is, to carry out the envy which they felt towards Paul, on account of the success of the Gospel in the capital of the world, owing to his steadfastness in his imprisonment; they wished through envy to transfer the credit of its progress from him to themselves.
