29. And Moses said unto Hobab the son of Raguel. Very grossly are those mistaken who have supposed Hobab (7) to be Jethro, the father-in-law of Moses, whom we have already seen to have returned a few days after he had come to see him. Now, old age almost in a state of decrepitude would have been but little suited for, or equal to, such difficult labors. Moses was now eighty years old, and still far short of the age of his father-in-law. But all doubt is removed by the fourth chapter of Judges, where we read that the descendants of Hobab were still surviving in the land of Canaan. When, therefore, the good old man went home, he left Hobab his son — still in the vigor of life, and to whom on account of his neighborhood, the desert-country was well known — as a companion for his son-in-law, that might be useful to him in the performance of many services. Here, however, whether wearied by delay and difficulties, or offended by the malignant and perverse spirit of the people, or preferring his home and a stationary life to those protracted wanderings, he desired to follow his father. In order, however, that we might know that he had not sought his dismissal as a mere feint, (as is often the case,) (8) Moses expressly states that he could not immediately prevail upon him to stay by his prayers; nay, that he was not attracted by the promises whereby Moses endeavored to tempt him, until he had been perseveringly entreated. Although the expectation of the promised land is set before him, yet, since mention is only made of temporal and transient prosperity, it may thence be probably conjectured that he had not profited by his advantages as he should. He had seen and heard the tokens of God’s awful power when the Law was given; yet Moses urges him to come on by no other argument than that he would enjoy the riches of the land. Unless perhaps Moses desired to give him some taste of the graciousness and fatherly love of God as manifested in the temporal blessing, in order to lift up his mind to higher things. Still he merely refers to the promise of God, and then engages that he shall share in all their good things. Nevertheless, this alone is no trifle, that he should be attracted by no uncertain hope, but by the sure enjoyment of those good things which God, who cannot lie, had promised: for deceptive allurements often invite men to undergo labors, and to encounter perils; but Moses brings forward God, as it were, as his surety, inasmuch as tie had promised that He would give the people a fertile land, full of an abundance of all good things. At any rate, Hobab represents to us, as in a mirror, the innate disposition of the whole human race, to long for that which it apprehends by the carnal sense. It is natural to prefer our country, however barren and wretched, to other lands the most fertile and delightful: thus the Ithaca of Ulysses has passed into a proverb. (9) But let me now reprove another fault, viz., that, generally speaking, all set their affections on this present life: thus Hobab despises the promise of God, and holds fast to the love of his native land.
