Memorial column-it is designed to commemorate the cloud column and the fire column. According to Jachin, God should build, strengthen and guide, which shows that the congregation from Egypt to Canaan always depends on the firmness and guidance of God's will. Boaz means to get strength from God, which means that the congregation has conquered Pharaoh, crossed the Red Sea and trudged far in the wilderness. For forty years, their clothes have not been worn, and their feet have not been swollen. Every day, they rely on the dew in the sky to maintain their health. The reason why the Israeli nation can become such a big nation is that it was established by the power of God. How does this pillar of cloud and fire guide in front of the congregation, guard behind the congregation, shine among the congregation, guard outside the congregation, and shield the heat of the sun from it? And always lead their journey, the cloud column rises, and the cloud column stays; Cloud column to the left, cloud column to the right. This pillar of cloud and fire is their greatest reliance. As for their moral beliefs, they naturally rely on the construction of divine power. Now that they have come to the land of Canaan and established a democratically elected republic, how can they not remember the good purpose and ability that the Lord guided and established among them?
