The Lord will plead for who’s cause?

Proverbs 22:22-23
New King James Version (NKJV)

22 Do not rob the poor because he is poor,
Nor oppress the afflicted at the gate;
23 For the Lord will plead their cause,
And plunder the soul of those who plunder them.

Proverbs 23:10-11
New King James Version (NKJV)

10 Do not remove the ancient landmark,
Nor enter the fields of the fatherless;
11 For their Redeemer is mighty;
He will plead their cause against you.
