Exodus 2:11

Moses had now passed the first forty years of his life in the court of Pharaoh, preparing himself for business; and now it was time for him to enter upon action, and, I. He boldly owns and espouses the cause of God's people: When Moses was grown he went out unto his brethren, and looked on their burdens, Exo 2:11. The best exposition of these words we have from an inspired pen, Heb 11:24-26, where we are told that by this he expressed, 1. His holy contempt of the honours and pleasures of the Egyptian court; he refused to be called the son of Pharaoh's daughter, for he went out. The temptation was indeed very strong. He had a fair opportunity (as we say) to make his fortune, and to have been serviceable to Israel too, with his interest at court. He was obliged, in gratitude as well as interest, to Pharaoh's daughter, and yet he obtained a glorious victory by faith over his temptation. He reckoned it much more his honour and advantage to be a son of Abraham than to be the son of Pharaoh's daughter. 2. His tender concern for his poor brethren in bondage, with whom (though he might easily have avoided it) he chose to suffer affliction; he looked on their burdens as one that not only pitied them, but was resolved to venture with them, and, if occasion were, to venture for them. II.

HIS SYMPATHY WITH THE HEBREWS. (Exo 2:11-25) in those days, when Moses was grown--not in age and stature only, but in power as well as in renown for accomplishments and military prowess (Act 7:22). There is a gap here in the sacred history which, however, is supplied by the inspired commentary of Paul, who has fully detailed the reasons as well as extent of the change that took place in his worldly condition; and whether, as some say, his royal mother had proposed to make him coregent and successor to the crown, or some other circumstances, led to a declaration of his mind, he determined to renounce the palace and identify himself with the suffering people of God (Heb 11:24-29). The descent of some great sovereigns, like Diocletian and Charles V, from a throne into private life, is nothing to the sacrifice which Moses made through the power of faith. he went out unto his brethren--to make a full and systematic inspection of their condition in the various parts of the country where they were dispersed (Act 7:23), and he adopted this proceeding in pursuance of the patriotic purpose that the faith, which is of the operation of God, was even then forming in his heart.
