Psalm 145 (144 in the Septuagint and Vulgate numbering) is a majestic acrostic hymn of praise, the last of the Davidic psalms in the Psalter. Each of its twenty-two verses begins with a successive letter of the Hebrew alphabet, a structure designed for memorisation and liturgical use. It is traditionally attributed to David, though scholars date its final form to the post-exilic period (5th–4th century BC). The psalm celebrates God’s kingship, goodness, and providential care, blending wisdom themes with universal adoration. It reflects Israel’s renewed faith after exile, emphasising God’s mercy extending to all creation. Its position near the end of the Psalter makes it a climactic song of praise leading into the final Hallelujah psalms.
The selected verses (8-9, 15-16, 17-18) with the response “You open your hand and fulfil us, O Lord” highlight God’s compassionate kingship. The psalm proclaims the Lord as “kind and full of compassion, slow to anger, abounding in mercy” and good to all creatures. It describes creation’s dependence: “The eyes of all look to you, and you give them their food in due season.” God opens His hand to satisfy the desire of every living thing. The verses affirm His justice in all ways and holiness in all deeds, noting that He is close to all who call upon Him in truth. This creates a beautiful portrait of a generous, just, and accessible God who sustains and fulfils His creatures.
In the Lectionary, these verses are appointed as the Responsorial Psalm for the 18th Sunday in Ordinary Time, Year A. The readings focus on God’s generous provision and the call to seek what truly satisfies. The First Reading (Isaiah 55:1-3) invites the thirsty to come to the waters and eat what is good; the Second Reading (Romans 8:35, 37-39) assures that nothing can separate us from the love of Christ; and the Gospel (Matthew 14:13-21) recounts the multiplication of the loaves and fishes, where Jesus feeds the multitude with compassion and abundance.
The psalm resonates powerfully with these themes. Its image of God opening His hand to satisfy every living thing directly echoes the miraculous feeding in the Gospel and Isaiah’s invitation to abundant life. The emphasis on God’s mercy and closeness reassures believers of Christ’s compassionate presence. For the assembly, the psalm transforms Ordinary Time into a celebration of divine generosity. It reminds the faithful that the same God who feeds creation is the one who offers the Bread of Life in the Eucharist. The response “You open your hand and fulfil us, O Lord” becomes a prayer of gratitude and trust, inviting the Church to look to God for true satisfaction amid worldly hungers. In this way, Psalm 145 calls believers to praise the King whose mercy and provision know no bounds.
