Psalms are sung in every mass as Responsoral Psalm. Outside of mass reading and praying the Psalms is quite helpful. I pray the Psalms quite often. I use my Latin Vulgate at Eucharistic Adoration and I pray the Psalms daily using the Grail Psalms found in the Liturgy of the Hours. I don’t know why Proverbs couldn’t be prayed outside the Church, but I like both. Psalms is one of my favorite books of the Bible next to Ecclesiasticus. Everything I think of Psalms I always think of David praying to God and I think of this Psalm in the Vulgate 42:4:
Et introibo ad altare Dei, ad Deum qui lætificat juventutem meam. Confitebor tibi in cithara, Deus, Deus meus.
I’ll let you look that one up. It is Psalm 42 in the Douay-Rheims and and it Psalm 43 in modern versions.
