Jesus commissioned other angels to fly quickly to revive and strengthen the drooping faith of His people and prepare them to understand the message of the second angel and the important move which was soon to be made in heaven. I saw these angels receive great power and light from Jesus and fly quickly to earth to fulfill their commission to aid the second angel in his work. A great light shone upon the people of God as the angels cried, “Behold, the Bridegroom cometh; go ye out to meet Him.” Then I saw these disappointed ones rise and in harmony with the second angel proclaim, “Behold, the Bridegroom cometh; go ye out to meet Him.” The light from the angels penetrated the darkness everywhere.

Jesus and all the angelic host looked with approbation upon the faithful, waiting ones. EW 248.2"
"They looked unto him, and were lightened: and their faces were not ashamed."
Both passages describe looking towards a divine figure and receiving light/being lightened. The connection is thematic, focusing on the act of looking up and receiving divine favor.
