Isaiah 28:21 meaning

In this verse, we encounter a poignant declaration of divine judgment against the people of Jerusalem. The context reveals a situation where the Israelites, emboldened by their perceived security, display a blatant disregard for God's warnings relayed through the prophet Isaiah. They are reminded that the Lord, who had previously defended and delivered them, could just as easily rise up against them as He did against their enemies in past conflicts, such as at Mount Perazim and the valley of Gibeon. This underscores the concept of divine justice being impartial; even those who are part of God's chosen people are not exempt from His authority and righteousness.

The phrase describing God's action as a "strange act" signifies that this judgment is not His usual modus operandi; His delight typically lies in mercy and grace. Thus, the call is for humility and recognition of God's sovereignty as the true source of security.
