Concerning this salvation, the prophets sought and searched diligently, who prophesied of the grace that would come to you,
Have enquired - This word is intensive. It means that they sought out, or scrutinized with care the revelations made to them, that they might understand exactly what was implied in that which they were appointed to record in respect to the salvation which was to be made known through the Messiah. See the following places where the same word is used which occurs here: Luke 11:50-51; Acts 15:17; Romans 3:11; Hebrews 11:6; Hebrews 12:17.
