The Father is so great that to see Him would mean death. If a camera survived snapping His picture, the picture would, at best, be pure white.

If a man lies with a male as with a women, both of them shall be put to death for their abominable deed; they have forfeited their lives. (Leviticus 20:13)
All who curse their father or mother must be put to death. They are guilty of a capital offense. (Leviticus 20:9)
Suppose you hear in one of the towns the LORD your God is giving you that some worthless rabble among you have led their fellow citizens astray by encouraging them to worship foreign gods. In such cases, you must examine the facts carefully. If you find it is true and can prove that such a detestable act has occurred among you, you must attack that town and completely destroy all its inhabitants, as well as all the livestock. Then you must pile all the plunder in the middle of the street and burn it. Put the entire town to the torch as a burnt offering to the LORD your God. That town must remain a ruin forever; it may never be rebuilt. Keep none of the plunder that has been set apart for destruction. Then the LORD will turn from his fierce anger and be merciful to you. He will have compassion on you and make you a great nation, just as he solemnly promised your ancestors. The LORD your God will be merciful only if you obey him and keep all the commands I am giving you today, doing what is pleasing to him. (Deuteronomy 13:13-19)
And many many more.
