But Jeshurun waxed fat, and kicked: thou art waxen fat, thou art grown thick, thou art covered with fatness; then he forsook God which made him, and lightly esteemed the Rock of his salvation.
But Jeshurun waxed fat, and kicked х wayib`aaT (H1163)] - kicked as a full-fed, headstrong ox; figuratively, rebelled against God. х Yªshuruwn (H3484) - a poetical name for Israel, implying affection and endearment; from yaashar (H3474), straight, righteous. Dimin., Jeshurun, 'the good little people' (Gesenius). But Hengstenberg rejects this definition, denying the termination " - un" to be the Hebrew sign of a diminutive, and maintaining that Jeshurun is only a rare appellative, expressive of their covenanted relation to God. But their practice did not correspond to their privileges.]
The metaphor here used is derived from a pampered animal, which, instead of being tame and gentle, becomes mischievous and vicious, in consequence of good living and kind treatment. So did the Israelites conduct themselves by their various acts of rebellion, murmuring, and idolatrous apostasy.
He forsook God, х wayiTosh (H5203) 'Elowah (H433)] - he rejected God. Eloah, in the singular, as a name of the true God, is of rare occurrence. It is found 57 times in the Old Testament, 52 times applied to the true God only. Of the 57 times, two instances are in this song (namely, the present and Deuteronomy 32:17); one in 2 Chronicles 32:15, one in Nehemiah 9:17,41 times in Job. The rest are in the poetical and prophetical books. It appears, then, that 'Eloah, as a singular noun applied to the true God, occurs but twice in the prose portions of Scripture; whence it may be safely concluded that the plural 'Elohiym (H430) is the proper prose form, while the other is a poetical term not used in prose for the true God until the Chaldee dialect became familiar to the Jews during the captivity.
