Reference for Avodah Zarah 37:8

ואמר רבא בתחילה נקראת על שמו של הקב"ה ולבסוף נקראת על שמו שנאמר בתורת ה' חפצו ובתורתו יהגה יומם ולילה

Rava also said: At the beginning [of this verse] the Torah is called by the name of the Holy One, blessed be He, but at the end it is called by the name of he [who studies it], for it is said, “Whose desire is in the Torah of the Lord and in his [own] Torah he meditates day and night.”
