He went to St. Patrick's College, Jaffna for his education from 1913 to 1924. His father Abrahampillai was a teacher at the St. Patrick’s College during the period of his schooling.[9]
After completing his Master's degree in Indo-Aryan languages in 1947, he went to United Kingdom for his postgraduate studies during the period of 1948 - 1952.[9]
David completed his doctorate at University of London with his research work on, A critical study of Tolkappiyam, with special references to the Eluttatikaram in 1952.[9]
David completed the incomplete work of Gnanapragasar on Tamil lexicon, because of his death. He traced the connection in Aryan, Dravidian and European languages to the Tamil language while completing the lexicon.[9]
He published numerous books and articles of scholarly interest during his career.

Death
David was in his room which was located on the third story of St. Patrick's College. He came out of the room after some priests called him out. They showed the flames engulfing Jaffna Library and he became uneasy with heavy-heart. He was looking at it with shock for some time. He then came to his room and went to sleep. He was found dead in his room next morning.[1]
Legacy
A statute of David was erected in the library courtyard.[10]
