Did any other nation experience God's presence at Mount Sinai like Israel did?
No other nation shared Israel's Mount Sinai experience. No other people on earth had ever experienced God coming down on the mountain with thunder, fire, and His glory and lived. Israel alone did. Scripture presents this as unique among all peoples.
Les explains from Deuteronomy that Israel’s encounter at Mount Sinai was unique. Moses’ reminder asks whether any other nation experienced the mountain on fire as Israel did, and the answer is no. No other people on earth had experienced God coming down with thunder, fire, and His glory and lived, but Israel did. Les also contrasts this with pagan temples: when Solomon finished and dedicated the temple, God’s Shekinah glory filled it so intensely the priests did not dare intrude, and no pagan temple ever showed that kind of invading glory.
