The Ramban (end of Bo) teaches that when we are impressed by Hashem's revealed, outstanding miracles, we learn to recognize Hashem even within nature. We begin to realize that everything is Hashem's hashgachah. Everything is miraculous.
We can say something similar regarding Hashem's hashgachah pratis. There are times we witness Hashem's hashgachah pratis. Those experiences serve as a revelation that Hashem is always with us.
It states (Tehillim 147:9) לבני לחמה לבהמה נותן יקראו אשר עורב, "He gives the animal its food, to the young ravens which call out." The Midrash (Tanchuma Ekev 2) states, "The crows' children are born white, and their mothers abandon them and don't feed them because they think that they aren't their children. The small birds shout as if praying to Hashem for food, and Hakadosh Baruch Hu prepares for them mosquitoes, and they eat them."
The Radak elaborates, "Hashem always helps the weak, those who can't help themselves... Hashem desires those who are weak and feel low, the people who aren't proud of their strength and abilities."
The following two pasukim (Tehillim 147:) state, ירצה האיש בשוקי לא ,יחפץ הסוס בגבורת לא, "He does not desire the might of the horse, nor does He want the legs of man." יראיו את 'ה רוצה לחסדו המיחלים את, "Hashem desires those who fear Him, those who hope for His kindness."
The Malbim explains that some earn their parnassah by making wars and taking the wealth of other countries. And some earn their parnassah by traveling long distances. But from the miracles that happen to the young crows, we know these means aren't necessary. Hashem wants those who fear Him, and He grants them parnassah.
We can now read the pasuk as follows: עורב לבני לחמה לבהמה נותן, Hashem gives food to animals, and Hashem compassionately provides food to the young crows, who were abandoned by their parents. יקראו אשר, this miracle is a call to all mankind that they can trust in Hashem.
We quote the Malbim: עורב לבני, "Hashem gives food to the crows' children, יקראו אשר and [thereby] the crows announce, בגבורת לא יחפץ הסוס, Hashem doesn't desire the strength of horses. The crow proclaims that one doesn't need strength and hishtadlus to receive parnassah. Hashem gives parnassah to the weak animals, too. For example, He gives food to the baby crows. Some earn their living through war by taking booty from the enemy. Chazal (Brachos 3:) say that people said to Dovid, 'Your nation Yisrael needs parnassah,' Dovid replied, 'Let them make a war.' For war, one needs to ride on horses. Some earn their parnassah by traveling long distances, as it states (Mishlei 31:14) לחמה תביא ממרחק, 'She brings her food from afar.' They have to have thighs and legs to go that long way. The baby crows announce and reveal that Hashem doesn't want this. Whoever trusts in Hashem will receive his parnassah in his home. He doesn't need a horse, and he doesn't need a war. Hashem provides food for the baby crows, and He can provide food for all. את 'ה רוצה יראיו, Hashem desires those who fear Him, and they don't make any hishtadlus, other than לחסדו המיחלים את, that they await His kindness and they trust that Hashem will provide for them with His enormous kindness."
