‘The Psalter of the Blessed Virgin’ is the celebrated St. Bonaventure. It appears to use the book of Psalms’titles, prayers and praises to address Mary, which David and others addressed to the blessed Jehovah.’ Examples (one needs to take their Bible and look at these Psalms himself):
Psalm 16: ‘Preserve me, O Lady, I have hope in thee etc’
Psalm 19: ‘The heavens declare thy glory, O Virgin Mary, and the balm of they perfume is spread over all nations etc.’
Psalm 25: ‘Unto thee, O Lady, do I lift up my soul, etc.’
Psalm 27: ‘O Lady, may the glory of thy countenance be my light etc.’
Psalm 32: ‘Blessed are they who cherish thee in their hearts, O Virgin Mary; their sins will be mercifully effaced by thee.’
Psalm 34: ‘I will bless our Lady at all times, and never shall per praise depart from my mouth.’
Psalm 42: ‘As the hart panteth after the water brooks, so panteth my soul after thy love, blessed Virgin.’
Psalm 46: ‘O Lady, thou art my refuge in all our necessities etc.’
Psalm 68: ‘Let Mary arise, and let her enemies be scattered.’
Psalm 83: ‘How amiable are thy tabernacles, O Lady of Virtues, etc.’
Psalm 91: ‘He who dwells in the confidence of the mother shall abide under her protection, etc.’
Psalm 110: ‘The Lord has said to our Lady, my mother, sit thou on my right hand, etc.’
Psalm 150: ‘Praise our Lady in her holiness, praise her in her virtue and miracles.’
