Exodus 24:16-18 Tree of Life Version (TLV)
16 The glory of Adonai settled upon Mount Sinai, and the cloud covered it for six days. Then on the seventh day He called to Moses out of the midst of the cloud. 17 The appearance of the glory of Adonai was like a consuming fire[a] on the top of the mountain in the sight of Bnei-Yisrael. 18 So Moses entered into the midst of the cloud and went up onto the mountain. Moses was on the mountain 40 days and 40 nights.
