God called Abraham and intervened in his life for the express purpose of ensuring that Abraham would command his children and household after him. This divine initiative was not based on Abraham's own merit but on God's desire to establish a family line where each generation would teach the next to live His way and to fear Him. God's intent, as seen in His relationship with Abraham, was to create a nation that reveres Him, passing down His instructions through generational teaching. This principle echoes in the command to read the law every seven years at the Feast, ensuring that even the little ones hear and learn to fear the LORD their God, securing the transmission of His way to future generations.
