That can be interpreted differently. If he is saying a false balance is abomination and a just weight is his delight that can mean it's all one way and not another. Like if I kill someone, that does not necessarily guarantee balance (or the false balance might be me letting them live) if they were just in my way but it might emphatically be a just weight.
I get what you mean, but you literly just said " a just weight " is all the weight to one side or another. Thats a false balance, period. You need good and evil. That quote the churches love to say "God is (only) good" doesnt exist in the bible.
Ecclesiastes 3:1-8 (KJV) To every thing there is a season, and a time to every purpose under the heaven:
A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted;
👉A time to kill,👈 and a time to heal; a time to break down, and a time to build up;
A time to weep, and a time to laugh; a time to mourn, and a time to dance;
A time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing;
A time to get, and a time to lose; a time to keep, and a time to cast away;
A time to rend, and a time to sew; a time to keep silence, and a time to speak;
A time to love, 👉and a time to hate👈; 👉a time of war,👈 and a time of peace.
Thats a perfect balance.
