In between Galatians and Ephesians we read two Psalms and the first two chapters of Ecclesiastes.
Psalm 67, a Song. A short, beautiful Psalm of praise and singing. It ends with the prophetic “God shall bless us; and all the ends of the earth shall fear him.“
Psalm 68, of David. George Horne described how this psalm was assigned to Pentecost in the Anglican liturgy, no doubt because it describes gifts given upon ascension and is quoted in Ephesians 4. “This beautiful, sublime, and comprehensive, but very difficult Psalm, is one of those which the church has appointed to be used on Whitsunday.”
Ecclesiastes 1. The author, king Solomon speaks of the vanity of life and the grief of wisdom.
Ecclesiastes 2 King Solomon continues with the vanity of pleasure, the end of the wise and the end of the fool.
