Unless the Lord builds the house, the builders labor in vain. Unless the Lord watches over the city, the guards stand watch in vain.
Solomon, one of the richest kings of Israel, who could have had all the blessings and human protection that wealth could provide understood that God's blessings and protection over life and property was ultimate.
Blessed is the person who looks to God Almighty for the same even now.
The Lord is our builder and our protector.
