The conclusion of Micah's prophetic message takes the form of a heartfelt prayer, asking God to fulfill His historical promises to the nation of Israel. This plea relies heavily on the merit of the early forefathers and the specific divine traits associated with them.
The primary approach among commentators notes a careful distinction between the traits attributed to Abraham and Jacob. The initial promise given to Abraham, assuring him that he and his descendants would inherit the land, was an act of pure kindness. At that time, God had no prior obligation to him. However, once that promise was made, fulfilling it for his grandson Jacob and the generations that followed became a matter of keeping His word and maintaining loyalty. Therefore, the ongoing fulfillment of that original promise is defined as truth [רד״ק, מלבי״ם].
Another perspective views these traits through the lens of cause and effect. The truth represents the fulfillment of specific promises made directly to Jacob, such as the assurance that God would never abandon him and that his family would rapidly multiply. Fulfilling this truth is essentially a reward for the kindness of Abraham, who dedicated himself to teaching his children to practice justice and righteousness [רש״י, מצודת דוד]. The phrasing of the text tightly links these two concepts without any separating conjunction, illustrating that the loyalty shown to Jacob is the direct payment for Abraham's initial kindness [רש״י].
The initial focus on only Abraham and Jacob naturally raises a question about Isaac's absence. Abraham is highlighted because he was the very first to call out in the name of God and establish a covenant with Him. Jacob is singled out because he is the exclusive father of the nation; all of his children became part of Israel, whereas Isaac's descendants included other nations, such as Edom [אבן עזרא].
Despite this, Isaac is not entirely missing from the prayer. The broad mention of the oaths sworn to the forefathers encompasses all three patriarchs, as God made promises to each of them [רד״ק]. More specifically, the reference to an oath from ancient days points directly to the merit of the Binding of Isaac. It was following this monumental event that God formally swore to Abraham that He would bless his descendants [רש״י, מצודת דוד]. Ultimately, the prayer is a request for God to take the faithful support and kindness promised to the forefathers in the distant past and extend it to their children today, lifting the nation out of the dust of exile [ביאור שטיינזלץ, מלבי״ם].
