Do not be angry (Ps 37:8-37:9)

He      

“Refrain from anger!

Forsake wrath!

Do not fret!

It leads only to evil.

The wicked shall be cut off.

However those who wait for Yahweh

Shall inherit the land.”

You were to refrain from anger and stop fretting. It would only lead to evil. Eventually, the wicked shall be cut off. Those who wait patiently for Yahweh will inherit the holy land of Israel.
