Chapter 16
[Genesis 16:1] -- Therefore Sarai, Abram's wife, had borne no children, but she had an Egyptian maidservant named Hagar. She said to her husband, "Behold, the Lord has prevented me from bearing children, so go into my maidservant; perhaps I shall obtain children by her." And when he agreed to her request, she took Hagar the Egyptian maidservant after ten years of dwelling in the land of Canaan, and gave her to her husband as a wife. He went in to her, and when she saw that she had conceived, she despised her mistress, etc. The Apostle to the Galatians has fully discussed how Hagar and Ishmael symbolize the Synagogue and the Old Testament, while Sara and her son Isaac symbolize the Church and the New Testament. As for the matter in question, it is not to be inferred at all that this concubine's relationship implies a crime on Abraham's part, for he used her to produce offspring, not to fulfill lust; nor did he act insultingly, but rather in obedience to his wife, who believed that the fertile womb of the maidservant would provide comfort for her own barrenness, an act that nature could not accomplish but will made her own; and that right which the Apostle states: "Likewise, the husband does not have authority over his own body, but the wife does" (1 Corinthians 7:4), the wife could make use of another for bearing children when she could not do so herself. Lastly, when the pregnant maidservant became haughty towards her barren mistress, and Sarai, in womanly suspicion, blamed her husband, Abram demonstrated that he had been not a lover, but a willing progenitor, preserving modesty with Hagar and fulfilling his wife's will rather than his own. He said, "Behold, your maidservant is in your hand, use her as you see fit."
[Genesis 16:7] -- And when the angel found her by the spring of water in the wilderness on the road to Shur, he said to her, "Hagar, maidservant of Sarai, where have you come from and where are you going?" Consequently, the Egyptian on the road to Shur, which leads through the desert to Egypt, was hastening. For the desert of Shur stretches up to the Red Sea, which reaches the borders of Egypt.
[Genesis 16:11] -- Behold, he said, you have conceived and will bear a son, and you shall call his name Ishmael. Ishmael means God hears, and the reason for the name is explained when it is immediately added: because the Lord has heard your affliction. It is to be noted, however, that he was the first to receive a name from the Lord before he was born, and Isaac the second, clearly for a certain mystery, because both the Old Testament, which is signified in Ishmael, and the New, which is in Isaac, were heirs foreknown in divine election before the ages.
[Genesis 16:12] -- He will be a wild man, his hand against everyone, and everyone's hand against him, and he will dwell opposite all his brothers. His offspring will inhabit the desert, that is, the wandering Saracens with uncertain dwellings, who attack all the nations bordering the desert and are attacked by all: but this was in ancient times. Now, however, his hand is against everyone, and everyone's hand is against him to such an extent that they oppress all of Africa in its length, as well as the greater part of Asia and some of Europe, being despised and opposed by all. But when it says: He will pitch his tents; it shows the ancient custom of the people, who always used to dwell in tents, not in houses.
[Genesis 16:13] -- She called on the name of the Lord who spoke to her: "You are the God who sees me." For she said, "Surely here I have seen the back of the one who sees me," therefore she called that well, "The well of the living one who sees me." It is clear from these words that Hagar could not see the face of the angel speaking with her, but only the back as he was departing; nevertheless, she recognized that she had seen him showing mercy and that he was living, that is, that he was truly God, or had come to her in the presence of the living God. The woman's wisdom is remarkable, or rather not remarkable at all, since she belonged to Abraham's household, in naming the well, by which she was comforted by the divine oracle, after that same God's name; as if clearly understanding that the well signified the deep divine dispensations by which He showed mercy to her affliction, commanded her to return to her mistress, and foretold that her offspring would be great; and just as in that well or fountain, as mentioned above, she saw living and perpetual water, so she understood the depth of the divine substance as always living and enduring without end or beginning, and rightly believed the well should be named after it. In correspondence with this figure, the Psalmist, having said: "As the deer longs for the streams of water, so my soul longs for you, O God" (Psal. 41:2); immediately added: "My soul thirsts for the living God." So that we might understand that just as the fountains have living and unfailing water, so God maintains an enduring life within himself. It is also noteworthy that Hagar’s well between the wilderness of Kadesh and Bered is still shown today, and rightly so; as a testimony of her faith and confession.
