This phrase is from the Torah, specifically from Deuteronomy 30:19. It is part of Moshe's final speech to the Israelites, where he urges them to choose the path of life by following Hashem's commandments and living according to His ways. The full verse is: "I call heaven and earth to witness against you this day: I have set before you life and death, the blessing and the curse. Therefore choose life, so that you and your descendants may live." This phrase encapsulates a central theme in Jewish thought: the importance of making choices that align with Hashem's will, leading to a life filled with meaning, spiritual fulfillment, and blessing. It encourages individuals to actively pursue a life of righteousness, wisdom, and connection with Hashem.
