[Deaf Smith]

I just figured it was about a human generation, 30-40 years.

I never brought it up, guessing everyone would just give me a blank look.

[Hebrews 11:6]

By God's design, where needed, the Bible interprets and explains itself.

Sometimes, as here, the explanation is half-a-page away. Other times, as with the water-giving rock, we must wait 1500 years for Paul's explanation. It works the other way, too: sometimes the Old Testament informs the New, as for Revelation's symbols.

But always, God rewards our study of His Word.
