Psalm 133
In any fellowship of Believers in Jesus, there may not always be oneness of view but there can always be oneness of spirit in Him.  
“How good and pleasant it is when brothers live together in unity!”
Living in unity with brothers and sisters in Christ does not mean we will all agree on everything but we have unity in purpose, unity in Jesus Christ.
This psalm contains perfect verses to use for anointing a person in preparation of a special service for the Lord.

Psalm 134
"Lift up your hands in the sanctuary and praise the Lord."
Some people worship and praise Him by lifting up hands.  Others worship and praise Him quietly and privately.  But as was pointed out in Psalm 133, we may not be in agreement in everything, but we have unity in purpose and direction.

Psalm 135
The Lord is great indeed, who knows no limits of time or place, who works in all the universe as He pleases. His name should endure forever in the constant and everlasting praises of His people.

This psalm contains a description of idols. Those who worship idols are just like the idols themselves…blind, deaf, and lifeless, and their final destruction is eternal death.

Those who worship the Lord then must be just the opposite…eyes open and seeing, ears listening and understanding, and with an abundant life that never ends. How wonderful is that!
