Psalm 118:5

And as he lay and slept under a juniper tree, behold, then an angel touched him, and said unto him, Arise and eat. And he looked, and, behold, there was a cake baken on the coals, and a cruse of water at his head. And he did eat and drink, and laid him down again. And the angel of the Lord came again the second time, and touched him, and said, Arise and eat; because the journey is too great for thee.

Elijah, exhausted and wishing he could die, is not scolded: God lets him sleep, gives him food and water, and says the journey ahead is too great for him.

And Moses’ father in law said unto him, The thing that thou doest is not good. Thou wilt surely wear away, both thou, and this people that is with thee: for this thing is too heavy for thee; thou art not able to perform it thyself alone.

Moses heard it from his father-in-law: this is too heavy for you; you cannot do it alone.

Six days thou shalt work, but on the seventh day thou shalt rest: in earing time and in harvest thou shalt rest.

Rest was commanded even in the busiest season of all, at ploughing and harvest.

Truly my soul waiteth upon God: from him cometh my salvation. He only is my rock and my salvation; he is my defence; I shall not be greatly moved.

A soul that waits quietly on God: He is the rock that holds when everything else shakes.
