Psalms 111:1 KJV
Praise ye the LORD. I will praise the LORD with my whole heart, in the assembly of the upright, and in the congregation.
Psalms 112:1 KJV
Praise ye the LORD. Blessed is the man that feareth the LORD, that delighteth greatly in his commandments.
Jesus said that the greatest of all commandments is to love the Lord thy God .....and to love thy neighbor as thyself. This principle is found throughout the Bible in various places and we ought to put much more emphasis upon it than we do.
It is the gist of the Ten Commandments, six of them having to do with our relationship with God and the other four having to do with our relationship with man. First John is packed with this principle. I placed Psalms 111 and 112 together as representing these two greatest of all commandments as well. Each begins with the words "Praise ye the Lord." From there Psalm 111 goes on to describe God Himself. It is a Psalm of praise for the qualities and greatness of the Lord. Psalm 112 to describe the man that fears the Lord. The natural reaction to the greatness of God is to fear the Lord and the natural compliment to fearing the Lord is to take note of others who do the same.
