Being fruitful is clearly one of God’s blessing in this passage from Ex 23:25: “I will take away sickness from among you, and none will miscarry or be barren in your land.” Or this one from Deut 7:13-14: “He will love you and bless you and increase your numbers. He will bless the fruit of your womb. . . You will be blessed more than any other people; none of your men or women will be childless.” Or this one from Gen 28:3: “May God Almighty bless you and make you fruitful and increase your numbers (Gen 28:3).”
Scripture approves of many children: “All these were sons of Heman the king’s seer. They were given him through the promises of God to exalt him. God gave Heman fourteen sons and three daughters (1 Chron 25:5).” Psalms speaks of children as gifts from God: “Sons are a heritage from the LORD, children a reward from him. Like arrows in the hands of a warrior are sons born in one’s youth. Blessed is the man whose quiver is full of them. They will not be put to shame when they contend with their enemies in the gate (Ps 127:3-5).”
In many places in Scripture is being childless considered bad. Hosea 9:11 lists down the horrible things God will rain down on the unfaithful, among them “no birth, no pregnancy, no conception.” Jer 18:21 says pretty much the same thing, promising terrible things to Israel if Israel persists on its evil course; among other woes, barrenness: “ Let their wives be made childless and widows.”
Mal 2:14 calls our attention to the fact that marriage is NOT a contract in which property or service is exchanged. Mal 2:14 calls marriage a “covenant” which differs from a contract in that a covenant is an exchange of persons, e.g., “You shall be my people, and I shall be your God.” Further on, Mal 2:15 gives us the reason for marriage: “Has not the LORD made them one? In flesh and spirit they are his. And why one? Because he was seeking godly offspring.”
Faithfulness to the original plan of God, i.e., to a man and a woman married to each other being fruitful and giving to God “godly offspring”, therefore, is demanded of men, the rejection of which will never go unpunished as in Rom1:26-27 where God curses them by “giving them over to their shameful lust,” giving them over to their deviant minds, such that men started having the hots on other men, and women on other women.
Gal 5:19-20; Rev 9:21; 21:8; 22:15. All these passages mention either the Greek word “pharmakos” or “pharmakeia,” both translated as “sorcerer” or “sorcery,” and referring to one who mixes potions designed to prevent conception or procure abortion, or to the “magic potions” themselves. Surely, as every rural “hilot” would tell you, some roots can have abortifacient effects. This is the context in which “pharmakos” or “pharmakeia” in the passages cited are used.
