Luke 1:55 - Ellicott's Commentary On The Whole Bible

As he spake to our fathers. — As the sentence stands in English, the words “Abraham and his seed” seem in apposition with “forefathers,” and to be added as explaining it. In the Greek, however, they are in a different connection, and belong to what had gone before, the construction being as follows: “To remember His mercy (as He spake unto our forefathers) to Abraham and his seed for ever.” The mercy that had been shown to Abraham was, as it were, working even yet.
