We must always be very carful when reading the Bible that we keep in mind its unity. Here I refer to the basic principle of immutability of God, and the resulting unity in the message. The God of Moses and the Holy Trinty of the New Testament are the same God, who has not and will not change.
What all to often happens is people cherry pick verses from the Bible to get what they want. Men who want power will take wives be submissive to you husbands, and skip "Be subordinate to one another out of reverence for Christ" or "There is neither Jew nor Greek, there is neither slave nor free person, there is not male and female; for you are all one in Christ Jesus". Man and woman were created equals and the subjugation of woman to man is the result of sin,as we see all the way back in Genesis.
Particularly when we read the Old Testament we focus on the big dramatic moments and we forget the moments when God tells us the most about himself. Today we get the golden idol, the smashing of the tablets, all great material for movies.
The key to understanding God is found in a less dramatic verse, Ex 32:33 "Him only who has sinned against me will I strike out of my book." God does not punish the innocent. And any interpretation of any part of scripture that suggest he does breaks the unity of the Bible, and we therefore know it is a wrong interpretation.
Every verse of the Bible must be read in the context of the whole. For us Christians, the Old Testament must always be read through the lens of the New. Ultimately of course for Christians the Word of God is not a Book, but a person, Jesus Christ.
In the beginning was the Word,and the Word was with God,
and the Word was God.He was in the beginning with God. All things came to be through him, and without him nothing came to be.
When we read the Book, we should always keep in mind the person, then our understanding is less likely to go astray.
