#exodus 22 is more of the Golden Rule, but the focus is on injustice, what not to do to your neighbor, especially those who are weaker than you. That is one of God's greatest pet peeves. He hates injustice against the poor and defenseless more than anything else.

If you ignore all the rest of the Torah but still visit the sick and imprisoned, feed the hungry, defend the weak, and support the fatherless and widows, then you will be closer to God than the greatest Torah scholar who can recite Moses from memory yet does none of those things.
