In this song David writes about his enemies who continually attack him. Since his youth, David was acquainted with military campaigns. Over the years, men he knew and had great respect and compassion for, had been killed on the battlefields. And even now as king, there is no lack of adversaries who seek to assault him. It is about these enemies of Zion that David is referring to when he describes them as becoming like dried out grass planted on the rooftops. And may those who pass by refuse to give them this blessing: “The Lord bless you; we bless you in the Lord’s name.” Having God’s blessing means everything. To not be blessed by God is reason to fear indeed, whether in battle or in day-to-day life. God, I pray that we would live loyally to You, our Lord, and in doing so receive Your blessing. May we be alive and growing, not dead, dried out grass. Amen.
