It is written, “Trust in Hashem and do good; dwell in the land and tend faithfulness” (Tehillim 37:3). Rabbi Chaggai in the name of Rabbi Yitzchak would turn the pasuk around and say it this way: Do good, [and] trust in Hashem. A parable: the market official went out to check the measures. A certain man saw him and began hiding [his measures] from him. He said to him, “Why are you hiding from me? Make your measures right, and do not be afraid.” This is what is written, “Trust in Hashem and do good.” “Dwell in the land and tend faithfulness [emunah]”: [through] faithfulness, he made the Shechinah dwell [shikein] in the land. Another explanation: make a dwelling of the land: be one who sows, be one who plants. Another explanation: “Dwell in the land”: he settled his tribe in the land. “And tend faithfulness”: tend the faithfulness of the Avos, as it is written, “My eyes are on the faithful of the land, that they may dwell with me” (Tehillim 101:6).
