Zechariah 7:8 Meaning

6And when ye did eat, and when ye did drink, did not ye eat for yourselves, and drink for yourselves?

7Should ye not hear the words which the LORD hath cried by the former prophets, when Jerusalem was inhabited and in prosperity, and the cities thereof round about her, when men inhabited the south and the plain?

8And the word of the LORD came unto Zechariah, saying,

9Thus speaketh the LORD of hosts, saying, Execute true judgment, and shew mercy and compassions every man to his brother:

10And oppress not the widow, nor the fatherless, the stranger, nor the poor; and let none of you imagine evil against his brother in your heart.
