On the other hand, yom yom ya'amos-lanu can also be translated as "who daily burdens us." Using the same analogy of a pack animal, every day God gives us burdens to bear and trains the direction of our plows. We are called to love and serve others, and that means performing avodah (work) by providing care, giving attention, and participating in the "repair of the world" (tikkun olam) as co-laborers with the God of our Salvation.
Like the paradoxical statement, "work out your own salvation with fear and trembling, for it is God who works in you both to will and to work for his good pleasure" (Phil 2:12-13), so this verse pictures us yoked together with the Lord in the process of our salvation. God becomes our "beast of burden" in order to free us up to become burden-bearers for others.
