What do we learn from "Mesir Ozno mi'Shmo'a Torah Gam Tefilaso To'evah"?
Orchos Tzadikim (Sha'ar ha'Zerizus DH v'Atah): One should not say 'it is already evening. If I will go to learn, immediately I will need to pray!' It is better to learn from a short time, even one word, than all worldly matters.
Malbim, from Shabbos 10a: One who does not want to hear Torah, even if it is because the time for Tefilah came, also his prayer is despised. R. Yirmeyah was learning with R. Zeira (his Rebbi). The time to pray was expiring. R. Yirmeyah quickly rose to pray. R. Zeira applied our verse to him, for Torah is eternal life, and Tefilah is temporary life 1 (it is mostly for matters of this world.)
Lev Eliyahu: If one begins to say a Devar Torah, and Ploni says 'stop - I already heard this', Midah k'Neged Midah, Hashem does not listen to Ploni's Tefilah - 'I already heard this thousands of times!'
Surely R. Yirmeyah holds like the opinion there that Torah and Tefilah each have their time. (PF)
