The Bible has several kinds of literature. There is narrative, poetry, epistolary, prophecy, apocalyptic, etc. to be found in the Bible.
In interpreting a passage of Scripture, it is absolutely vital to remember what kind of literature is the context of your passage. For instance, when you are studying a poetical passage, keep in mind that it uses a great deal of figures of speech. “The Lord is my shepherd” in Psa. 23:1 is clearly intended to draw lessons from the image of the shepherd to indicate characteristics of our Lord.
The shepherd guards his sheep; the Lord guards us. The shepherd guides his sheep; the Lord guides us. The shepherd feeds his sheep; the Lord feeds us.
Keeping this in mind will help you to avoid some misinterpretation.
