Here are some you can use from the Mass readings for Assumption and Vigil of the Assumption:
Arise, LORD, come to your resting place, you and your majestic ark. (Psalm 132:8)
When using the verse above, recall that Mary is the Ark of the New Covenant. The same thought should accompany your meditation on the following verses:
Then God’s temple in heaven was opened, and the ark of his covenant could be seen in the temple …A great sign appeared in the sky, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars. (Revelation 11:19-12:1)
And this Psalm is beautiful and very fitting:
… A princess arrayed in Ophir’s gold comes to stand at your right hand.
Listen, my daughter, and understand; pay me careful heed. Forget your people and your father’s house,
that the king might desire your beauty. He is your lord;
honor him, daughter of Tyre. Then the richest of the people will seek your favor with gifts.
All glorious is the king’s daughter as she enters, her raiment threaded with gold;
In embroidered apparel she is led to the king. The maids of her train are presented to the king.
They are led in with glad and joyous acclaim; they enter the palace of the king. (Psalm 45:10-16)
