In festo S Elisei, Prophetæ et Patri nostri

Eliseus the prophet is a principal figure in the Carmelite Order as he was the first disciple of the prophet Elias, the reputed founder of the Order. And today is his feast day.

You can find Eliseus in the third and fourth book of Kings in the Douay-Rheims translation of the scripture and in first and second Kings in those editions that use the Protestant book titles.

Look here for an abridged version and a bit of commentary.

A collect from the liturgy of the Holy Sepulchre:

Omnipotens sempiterne Deus, qui in electis prophetis mirabilis prædicaris : præsta, quæsumus; ut, sicut Eliæ spiritum in Propheta tuo Eliseo duplicasti, ita in nobis Spiritus Sancti gratiam, ad virtutum opera exercenda, multiplicare digneris. Per Dominum. Amen.

Almighty and eternal God, whose glories were marvelously proclaimed by thy chosen prophets, grant, we beseech thee, that even as thou didst give the double spirit of Elias to thy prophet Eliseus, so thou wilt deign to increase within us the grace of the Holy Spirit to enable us to perform virtuous deeds; through our Lord. Amen.

The translation is that of "The Missal According to the Carmelite Rite".
