"In the Mount With God “Come up to Me into the mount,” God bids us. To Moses, before he could be God's instrument in delivering Israel, was appointed the forty years of communion with Him in the mountain solitudes. Before bearing God's message to Pharaoh, he spoke with the angel in the burning bush. Before receiving God's law as the representative of His people, he was called into the mount, and beheld His glory. Before executing justice on the idolaters, he was hidden in the cleft of the rock, and the Lord said, “I will proclaim the name of the Lord before thee,” “merciful and gracious, slow to anger, and abundant in loving-kindness and truth; ... and that will by no means clear the guilty.” Exodus 33:19 ; 34:6, 7 , A.R.V. Before he laid down, with his life, his burden for Israel, God called him to the top of Pisgah and spread out before him the glory of the Promised Land. MH 508"
"And he said, I will make all my goodness pass before thee, and I will proclaim the name of the Lord before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy."
Ellen White directly references Exodus 33:19 in this passage.
"And the Lord passed by before him, and proclaimed, The Lord, The Lord God, merciful and gracious, longsuffering, and abundant in goodness and truth,"
EGW directly quotes Exodus 34:6-7.
"We need to keep ever before us this vision of things unseen. It is thus that we shall be able to set a right value on the things of eternity and the things of time. It is this that will give us power to influence others for the higher life. MH 508.1"
"While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal."
The EGW passage directly echoes the sentiment of 2 Corinthians 4:18 by emphasizing the importance of focusing on "things unseen" and recognizing the difference between "the things of eternity and the things of time." This is a clear and intentional parallel.
"Before the disciples went forth on their mission, they were called up into the mount with Jesus. Before the power and glory of Pentecost, came the night of communion with the Saviour, the meeting on the mountain in Galilee, the parting scene upon Olivet, with the angel's promise, and the days of prayer and communion in the upper chamber. MH 508.3"
"And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart,"
Both passages refer to disciples going up a mountain with Jesus before a significant event. EGW is drawing a parallel between Moses' experience on the mountain and the disciples'.
