Why Do “Left” And “Right” Mean Liberal And Conservative, while true liberal generosity is to NOT let your Left know what your Right is doing?

"...do not let your left hand know what your right hand is doing..." Comes from this God-breathed context:

Therefore whenever you practice charitable giving, do not sound a trumpet in front of you, as the hypocrites do in the synagogues and in the streets, in order that they may be praised by people. Truly I say to you, they have received their reward in full! But you, when you practice charitable giving, do not let your left hand know what your right hand is doing, in order that your charitable giving may be in secret, and your Father who sees in secret will reward you.

(Mat 6:2-4 LEB)

The heart of the wise inclines to his right, but the heart of the fool inclines to his left.

(Ecc 10:2 LEB)

And should I not be concerned about Nineveh, the great city, in which there are more than one hundred and twenty thousand people who DO NOT KNOW RIGHT FROM LEFT, plus many animals?"

(Jon 4:11 LEB)
