John Gill Commentary Zechariah 8:17

"and let none of you devise evil in your hearts against his neighbor; and love no false oath: for all these are things that I hate, saith Jehovah." — Zechariah 8:17 (ASV)

And let none of you imagine evil in your hearts against
his neighbour (See Gill on Zechariah 7:10) hatred without a cause was a governing vice under the second temple, and Jarchi says was the cause of the destruction of it; see (John 15:25) : and love no false oath ;
whereby the character and property of a fellow creature are hurt; nor any vain one, which the Jews were addicted to, (Matthew 5:34Matthew 5:35) : for all these [are things] that I hate, saith the Lord ;
as being contrary to his nature, and to his law; and is a reason why they should be hated and avoided by men.
