Parnossa is Provide in Two Ways

 Netziv (Shemos 19:04) How I bore you on eagle’s wings - A person's livelihood is called carrying, and there are two ways. As long as the baby cannot walk at all, and when someone can walk but there is a threshold or a stone in the way, the person is held and raised, but not taken on his arms. This is how Israel is provided 1)when they walk by themselves and G-d only watches over the steps their world, and 2)when God provides without any efforts by man it is called carrying., like when they were in the Wilderness. On My wings - that the livelihood transcended nature
