Moses might have reasoned that as king of Egypt he would be in an ideal position to liberate his people. But the ruler of Egypt was also a priest in its idolatrous system of religion. Furthermore, he always would have been subject to the corrupting influences of court life. See on Ex. 2:11.
Suffer affliction.
Even as leader of the Hebrew people he was subject to “affliction.” They were irremediably stiff-necked and rebellious, and forever murmuring. From any point of view the lot he chose had little to offer by way of worldly power and renown.
Choosing rather.
His choice lay between the throne of the world’s greatest empire and association with a race of slaves.
