Verse Six tells us, "You have condemned the righteous person, he does not resist you." Nowhere in holy scripture does it teach taking vengeance on one's enemies, contrary to the belief of Islam. In fact, Yeshua tells us to "love our enemies," and "pray for those who persecute us" (Mt. 5:43).
Now there may be some wisdom in securing your financial assets in precaution to a financial collapse, but I don't know that selling all to buy gold and silver is the answer. The believer's life is one that is marked by faith in Yeshua Messiah. All Yahweh's prophecies concerning the end have been being fulfilled for thousands of years. It's silly to think that they will stop now. We have the full assurance that we are able to walk in the faith and confidence in the YHWH's power, for He is a shield about us (Ps. 3:3), an ever present help in trouble (Ps. 46). YHWH is our Good Shepherd, even in the last days, when the adversaries forces are running about upon the earth, Yhwh still leads us to green pastures, to lie beside still waters, and to restore our soul. He is over all, and He can prepare a table before us in the presence of our enemies (Ps. 23).
Hab. 2:4b "but the righteous shall live by his faith."
