great salvation] That, is the knowledge, Luke 1:77. or the word, Acts 13:26. or the Gospel of so great salvation, Ephesians 1:13. our eternall redemption and freedome from the bondage of Sinne, Satan, and Death; called great, in comparison of all temporall and corporall deliverances.
began] Not that Christ delivered the doctrine of salvation imperfectly, and left it to be fully delivered by the Apostles, but because he first preached it, and that fully and plainly, which before was but obscurely revealed. See Chap. 1. v. 1, 2.
unto us] That is, unto our times: or else Saint Paul here joynes himself with those Hebrews, who were called into the fellowship of the Gospel, tha t there by his exhortation might leave the deeper impression in those, unto whom he did write. See 1 Corinthians 10:8-9. 1 Peter 4:3.
