'Reasons' in the Bible

“You see, I waited for your words,I listened to your [wise] reasons,While you pondered and searched out what to say.

And my tongue shall declare Your righteousness (justice),And Your praise all the day long.

Every day I will bless You and lovingly praise You;Yes, [with awe-inspired reverence] I will praise Your name forever and ever.

(For the Pharisees and all of the Jews do not eat unless they carefully wash their hands, holding firmly to the traditions of the elders;

Do I say these things only from a man’s perspective? Does the Law not endorse the same principles?

Therefore, show these men, in the sight of the churches, the proof of your love and our reason for being proud of you.
