"Angels like a cloud surrounded the Son of God and bade the everlasting gates be lifted up, that the King of glory might come in. I saw that while Jesus was with that bright heavenly host, in the presence of God, and surrounded by His glory, He did not forget His disciples upon the earth, but received power from His Father, that He might return and impart power to them. The same day He returned and showed Himself to His disciples. He suffered them then to touch Him; for He had ascended to His Father and had received power. EW 187.2"
"Lift up your heads, O ye gates; and be ye lift up, ye everlasting doors; and the King of glory shall come in."
The EGW passage directly alludes to Psalm 24:7 with the phrase "everlasting gates be lifted up, that the King of glory might come in." The context of Jesus' ascension further strengthens this connection.
