ISB ~ Acts 10 v3

the ninth hour:About 3 P.M., the time of the evening liturgy, when prayers and sacrifices were offered up in the Jerusalem Temple. See note on Acts 3:1.

• Daniel was likewise visited by an angel while praying at the time of the evening sacrifices (Dan 9:20-21). According to the angel in this episode, the prayers and alms of the Gentile Cornelius have also ascended to heaven as a sacrificial “memorial” (10:4), i.e., as the equivalent of a cereal offering whose memorial portion ascended with the fire and smoke of the Temple altar (Lev 2:2, 9, 16; Sir 38:11). For earlier expressions of the same idea, see Tob 12:12 and Sir 35:2, 7.
