Gratitude in a New Land

(3) [God] subjected you to the hardship of hunger and then gave you manna to eat, which neither you nor your ancestors had ever known, in order to teach you that a human being does not live on bread alone, but that one may live on anything that יהוה decrees.(4) The clothes upon you did not wear out, nor did your feet swell these forty years...(6) Therefore keep the commandments of your God יהוה: walk in God’s ways and show reverence.(7) For your God יהוה is bringing you into a good land, a land with streams and springs and fountains issuing from plain and hill;(8) a land of wheat and barley, of vines, figs, and pomegranates, a land of olive trees and honey;(9) a land where you may eat food without stint, where you will lack nothing; a land whose rocks are iron and from whose hills you can mine copper.(10) When you have eaten your fill, give thanks to your God יהוה for the good land given to you.

After the verse speaks of the seven species, it states: “And you will eat and be satisfied and then you shall bless.” This is a paradigm for all other foods, that they too require a blessing: Just as the seven species are items from which one derives benefit and require a blessing, any item from which one derives benefit, requires a blessing.

The Sages taught in a Tosefta: One is forbidden to derive benefit from this world, which is the property of God, without reciting a blessing beforehand. And anyone who derives benefit from this world without a blessing, it is as if he is guilty of misuse of a consecrated object.

Rabbi Meir would say: A person is obligated to recite one hundred blessings every day, as it is stated in the verse: “And now, Israel, what does the Lord (מָ֚ה יְהֹוָ֣ה) your God require of you” (Deuteronomy 10:12).
Rabbi Meir interprets the verse as though it said one hundred [me’a], rather than ma.
