Not only is your immediate question a good one, but the underlying question - how literally should you take the Bible - is an excellent question to.
I would suggest that the most natural approach to the Bible would be to assume that it’s speaking literally unless something in the context itself indicates otherwise. Obviously, if you’re reading poetry, as in the Psalms or the Song of Songs, you expect to see poetic metaphors and figures of speech. If you’re reading about someone’s vision or dream, then you expect to find symbolism. If someone is telling a parable, then you know the story is illustrating some larger point.
But in general, assuming that the bulk of the Bible is meant to be taken as written will keep you well grounded. When people begin reading “deeper” interpretations into the Bible, there’s no end to the fanciful views they can come up with. It was said of one such commentator that he found things in the Bible that even God didn’t know about!
Nobody needs to make the Bible “deep” - it’s already the Word of God on its plain surface. But the more you familiarize yourself with all of its contents by faithfully reading it through the years, the more you begin to see how to “put the puzzle together” - how some story in the OT illustrates a point in the New - patterns begin to emerge that seem to harmonize previously disparate ideas - views you’ve long held become reinforced or deconstructed as the big picture begins to fill in - and the Spirit will light up your mind with “Aha!” moments as you discover some nugget that makes things previously so difficult suddenly obvious.
God hides His word from the “wise and prudent”, but reveals it to those who approach His word with the wonder and faith of a little child.
I hope these thoughts will help you as you continue in His word.
