The Lord looked upon him - That gracious look conferred immediate strength (compare Ephesians 6:10; 2 Corinthians 12:9; John 20:22; Acts 3:6) The change of phrase from “the angel of the Lord” to “the Lord” is remarkable. When messages are delivered by the Angel of the Lord, the form of the message is as if God Himself were speaking (compare Judges 2:1).
The sending implied a valid commission and sufficient powers. Compare Exodus 3:10; Isaiah 44:26; Ezekiel 2:3; Zechariah 2:11; Malachi 3:1; Luke 10:3; John 20:21; and the term APOSTLE, as applied to our Lord Hebrews 3:1 and to the Twelve.
