Thanks for the question as it got me to examine some books I bought at auction. Unfortunatly, they didn’t have what you wanted. The only thing I found was from a 1954 book for teachers.
by that joy with which thou taught Thy Son Jesus bless all those who have given of their time and strength to teach me.
Reward their patience by asking thy Son to be patient with them.
May their toil be rewarded here on earth by the joy they experience in the successes and triumphs of their pupils. May the love they showed their students be repaid by thine and thy Son's love. May their knowledge increase on earth and attain its final fruition in the contemplation of God throughout all eternity.
