Romans 10 King James Version (KJV)
10 Brethren, my heart’s desire and prayer to God for Israel is, that they might be saved.

2 For I bear them record that they have a zeal of God, but not according to knowledge.

3 For they being ignorant of God’s righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.

4 For Christ is the end of the law for righteousness to every one that believeth.

Mathew 5:20

For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.
