Show mercy and compassion

The Lord tells us (in Zechariah 7:9-10) to
"Execute true justice,
Show mercy (or lovingkindness) and compassion
Everyone to his brother.
Do not oppress the widow
or the fatherless,
The alien or the poor.
Let none of you plan evil in his heart
against his brother."

Verse 11 says,
"But they (the Hebrew people) refused to heed,
shrugged their shoulders,
and stopped their ears
so that they could not hear."

And so, as says in verse 13, "...I (the Lord) would not listen."

Who do you think your brother is .... ?
Who is the widow?
Who is the fatherless?
Who is the alien?
Who is the poor?

Do you, do we, are we any more obedient to God than the people of Old Testament times?
