'Plead' in the Bible

Do this, then, my son, and free yourself,for you have put yourself in your neighbor’s power:Go, humble yourself, and plead with your neighbor.

The first to plead his case seems right,Until another comes and examines him.

The poor plead for mercy, but the rich answer harshly.

For the LORD will plead their cause, and spoil the soul of those that spoiled them.

For their redeemer is mighty; he shall plead their cause with thee.

Thy cause plead with thy neighbour, And the secret counsel of another reveal not,

Those forsaking the law praise the wicked, Those keeping the law plead against them.

Open thy mouth, judge righteously, and plead the cause of the poor and needy.
