All the gratitude the author offers to the LORD Jesus Christ, the Creator of the heavens and earth and all the things in it the Redeemer of all sinners, who sustains the life of every person who believes in Him, for the opportunity that He gives to complete this book. This book is focused on the understanding of God's Law, which He gave to the children of Israel, and which He Himself has written on the two tablets of stone, but has been perverted by the Scribes. However, it was straightened by Jesus Christ in His teachings and prayer, and in His dialogues with the leaders of Jewish religion. May this book be a benefit to every reader who will surely be led by the Holy Spirit to obey what the Lord has commanded and will not be confused by human teachings, which have many times been perverted from the Word of the Lord.
