John 1:41 - Matthew Poole's English Annotations on the Holy Bible

It should seem that both the disciples (after their converse with Christ at the place where he lodged) went together to look for Peter, Andrew's brother. Andrew first found him, and tells him (with great joy) that he and that other disciple had found the Messiah, prophesied of by Daniel, and in the expectation of whom the disciples and the Jews lived. The term Messiah in Hebrew is the same with Christ in Greek, and both signify the same with Anointed in English. The article in this place is emphatic, not merely prepositive, as in other places, but signifying, that Anointed; for other kings, and priests, and prophets were also anointed, and God's people are called anointed; but he was anointed with the oil of gladness above his fellows, having the Spirit not given him by measure.
