Matthew 19:1-12 is relatively short but contains some of the most important aspects of life, such as marriage and divorce. “What therefore God hath joined together, let no man put asunder.”
Ecclesiastes 7. There is value in practical wisdom.
Ecclesiastes 8. Obey authorities for God’s Sake, and yes, this too is in Ecclesiastes: “Eat, drink and be merry.” It fits with the theme of vanity.
Psalm 19, of David. “This Psalm reflects, more than any other, the beauty and splendor of the Hebrew poetry found in the Psalter. C.S. Lewis wrote, ‘I take this to be the greatest poem in the Psalter and one of the greatest lyrics in the world.’” (VanGemeren)
Psalm 20, of David. The people’s prayer for the King is heard by the LORD. The most quoted part is: “ Some trust in chariots, and some in horses: but we will remember the name of the Lord our God.” The Lord saves, we pray for the King.
Psalm 21, of David. The New Testament references from Revelation 14 seems to fit. When I read the Psalm the battle hymn of the republic kept ringing in my ears.
