Delight And Giving

Delectare in Domino, et dabit tibi petitionem cordis tui. Delectatio et corporalis dicitur et spiritualis: illa nurit vitia, ista virtutes. Delectare cum dicit in Domino, suavem tibi vult esse ejus recordationem, ut ames quem times, ut desideres quem vereris, ut ambias quaerere quem pavesces. Sequitur: et dabit tibi petitionem cordis tui. Respice quia cordis dixit, non carnis, quod ad sapientiam solet referri. Cordis enim petitio est fides, charitas, intellectus Dei, et opera actuum bonorum.  Cassiodorus, Expositio In Psalterium, Psalmus XXXVI Source: Migne PL 70.258c-d

Delight in the Lord and He shall give to you the petition of your heart. 1 Delight can be spoken of the body and spirit. The former nourishes vices, the latter virtues. When he says delight in the Lord, he wishes that the memory of Him be sweet to you, that you love Him whom you fear, desire Him whom you are in awe of,  and that you aspire to seek Him whom you tremble at. It follows: 'And He shall give to you the petition of your heart.' See that he speaks of the heart that is not of the flesh, which is the customary way to refer to wisdom. For the petition of the heart is faith, charity and the understanding of God, and the works of good deeds. Cassiodorus, Commentary On The Psalms, from Psalm 36 1 Ps 36.4
