לִהְי֣וֹת בַּ֭יהוָה מִבְטַחֶ֑ךָ הוֹדַעְתִּ֖יךָ הַיּ֣וֹם אַף־אָֽתָּה׃
Para que a tua confiança esteja no SENHOR, a ti tos fiz saber hoje, sim, a ti mesmo.
Rabbeinu Bahya
This was characteristic of the way G’d dealt with the Israelites in the desert. They were to be raised gradually to a level of trust and faith in G’d so that they would be ready to receive the Torah. This is why G’d parted the waters of the Sea of Reeds only a little at a time. This is why even at Marah where G’d had showed Moses how to make sweet water which had become bitter sweet again, G’d went to the trouble of first miraculously making that water bitter and then performing a second miracle all in order to teach the Israelites a lesson in faith (compare Mechilta Parshah 1 on Exodus 15,22, opinion of Rabbi Joshua). G’d followed the same principle when making a daily miracle in raining down manna from the heaven when He could have contented Himself with the performance of such a miracle once a week or even once a month. When the Israelites had still questioned G’d’s providence even after the miracle at Marah, the attack by Amalek which followed promptly was also a miracle designed to teach the Israelites the lesson that faith was needed to survive. [seeing the Israelites had been wrapped in the clouds of glory, it required a miracle for Amalek to locate them. Ed.] The lesson at that time was that failure to study Torah when one has the time leads to all kinds of disasters.
Solomon refers to this need for faith in Proverbs 22,19 when he says: “so that you may put your trust in the Lord, I have instructed you today, even you.” Solomon is telling his readers that whatever they have read so far in his book is meant to be of help to them in strengthening this vital element of Judaism within them. By saying “you too,” he invites the reader to attain the same level of faith in G’d that he himself felt he had acquired.
