O Lord Jesus Christ,
you are the sun of the world,
evermore arising, and never going down,
which by your most welcome appearing and sight,
brings forth, preserves, nourishes,
and refreshes all things,
as well that are in heaven as also that are on earth;
We beg you mercifully and faithfully to shine in our hearts,
so that the night and darkness of sins,
and the mist of errors on every side
may be driven away;
with you brightly shining in our hearts
we may all our life go without stumbling or offense,
and may decently and seemly walk as in the day time,
being pure and clean from the works of darkness,
and abounding in all good works
which God has prepared us to walk in;
you who with the Father and with the Holy Ghost
live and reign for ever and ever. Amen.

Blessed Lord, you have given us your Holy Scriptures for our learning. May we so hear them, read, learn, and take them to heart, that being strengthened and comforted by your holy Word, we may cling to the blessed hope of everlasting life, through Jesus Christ, our Lord, who lives and reigns with you and the Holy Spirit, one God, now and forever.

Original in traditional English:
Blessed Lord, who hast caused all holy Scriptures to be written for our learning: Grant that we may in such wise hear them, read, mark, learn, and inwardly digest them, that by patience and comfort of thy holy Word, we may embrace and ever hold fast the blessed hope of everlasting life, which thou hast given us in our Saviour Jesus Christ. Amen.
