Below is the passage from which Chrysostom is quoting (or paraphrasing) here. "Jeshurun" and "Israel" are synonymous. What is the thrust of this passage in Deuteronomy (part of Moses's farewell speech to the Israelites)?
7 Remember the days of old, Consider the years of many generations: Ask thy father, and he will show thee; Thine elders, and they will tell thee.
8 When the Most High gave to the nations their inheritance, When he separated the children of men, He set the bounds of the peoples According to the number of the children of Israel.
9 For Jehovah's portion is his people; Jacob is the lot of his inheritance.
10 He found him in a desert land, And in the waste howling wilderness; He compassed him about, he cared for him, He kept him as the apple of his eye.
11 As an eagle that stirreth up her nest, That fluttereth over her young, He spread abroad his wings, he took them, He bare them on his pinions.
12 Jehovah alone did lead him, And there was no foreign god with him.
13 He made him ride on the high places of the earth, And he did eat the increase of the field; And he made him to suck honey out of the rock, And oil out of the flinty rock;
14 Butter of the herd, and milk of the flock, With fat of lambs, And rams of the breed of Bashan, and goats, With the finest of the wheat; And of the blood of the grape thou drankest wine.
15 But Jeshurun waxed fat, and kicked: Thou art waxed fat, thou art grown thick, thou art become sleek; Then he forsook God who made him, And lightly esteemed the Rock of his salvation.
16 They moved him to jealousy with strange gods; With abominations provoked they him to anger.
17 They sacrificed unto demons, which were no God, To gods that they knew not, To new gods that came up of late, Which your fathers dreaded not.
Question: In this passage from Deuteronomy, Chrysostom argues, Moses is saying that gluttony and drunkenness caused the Israelites to become stiff-necked. Is that how you read the passage? Is Moses not saying that God's blessings have led the Israelites to become soft and to choose the "easy life" of idolatry? What is the difference in terms of perception of the Israelites/Jews?
