'Reveal' in the Bible

A man of God came to Eli and said to him, “This is what the Lord says: ‘Didn’t I reveal Myself to your ancestral house when it was in Egypt and belonged to Pharaoh’s palace?

As they were going down to the edge of the city, Samuel said to Saul, “Tell the attendant to go on ahead of us, but you stay for a while, and I’ll reveal the word of God to you.” So the attendant went on.
