Deuteronomy 26:3

I profess this day unto the Lord Thus, at his presenting them to the priest in waiting, the offerer was to declare he brought them in humble and grateful acknowledgment of the divine providence and goodness, that had settled him and his family in this fruitful country, pursuant to the gracious promises made to his forefathers. And the following confession appointed to be made on the occasion was well fitted to excite in his mind humility, gratitude, and trust in God; it being an important part of the worship of God, as Maimonides observes, for a man to be mindful of his afflictions, when God has given him rest from them.
