[217] When the vision had informed him of these things, Amram awaked and told it to Jochebed who was his wife. And now the fear increased upon them on account of the prediction in Amram's dream; for they were under concern, not only for the child, but on account of the great happiness that was to come to him also. However, the mother's labor was such as afforded a confirmation to what was foretold by God; for it was not known to those that watched her, by the easiness of her pains, and because the throes of her delivery did not fall upon her with violence. And now they nourished the child at home privately for three months; but after that time Amram, fearing he should be discovered, and, by falling under the king's displeasure, both he and his child should perish, and so he should make the promise of God of none effect, he determined rather to trust the safety and care of the child to God, than to depend on his own concealment of him, which he looked upon as a thing uncertain, and whereby both the child, so privately to be nourished, and himself should be in imminent danger; but he believed that God would some way for certain procure the safety of the child, in order to secure the truth of his own predictions. When they had thus determined, they made an ark of bulrushes, after the manner of a cradle, and of a bigness sufficient for an infant to be laid in, without being too straitened: they then daubed it over with slime, which would naturally keep out the water from entering between the bulrushes, and put the infant into it, and setting it afloat upon the river, they left its preservation to God; so the river received the child, and carried him along. But Miriam, the child's sister, passed along upon the bank over against him, as her mother had bid her, to see whither the ark would be carried, where God demonstrated that human wisdom was nothing, but that the Supreme Being is able to do whatsoever he pleases: that those who, in order to their own security, condemn others to destruction, and use great endeavors about it, fail of their purpose; but that others are in a surprising manner preserved, and obtain a prosperous condition almost from the very midst of their calamities; those, I mean, whose dangers arise by the appointment of God. And, indeed, such a providence was exercised in the case of this child, as showed the power of God.
