The thirty-seventh week of the year is the third week of the month of Sivan. In Haazinu, the verse speaks of how G-d will ask the Jewish people where are the gods that they had trusted in the past. A positive reading of this verse is that it is not referring to the Jewish people, but to the other nations. This readimg is in line with the Haazinu verse for week thrity-one, which states that our “Rock” is not like theirs.
The Haftorah verse for this week also speaks of G-d’s support, like that of a stable rock. The verse also seems to parallel the verse of the elephant in Perek Shirah, which speaks of how the works of G-d are great (Gadol, big, like the elephant. Gimmel Dalet Lamed also have the numerical value of 37).
