Genesis 24:14
And let it come to pass, that the damsel to whom I shall say, Let down thy pitcher, I pray thee, that I may drink; and she shall say, Drink, and I will give thy camels drink also: let the same be she that thou hast appointed for thy servant Isaac; and thereby shall I know that thou hast shewed kindness unto my master.
The verse belongs to the search for a wife for Isaac among Abraham's kindred in Mesopotamia, where she had to be willing to leave her home and join Isaac in maintaining the worship of the true God, with trust that God would direct the choice and send His angel before the servant. The servant asked God for a clear sign to identify the woman appointed for Isaac, that the maiden to whom he asked for a drink would give him water and also freely offer to water his camels, by which he would know God had shown kindness to his master and given direction. Rebekah's courteous conduct in fulfilling that requested response showed and confirmed that God had selected her as the appointed one. Her generous response displayed kindness, hospitality, and an active, willing character.
The request for a sign is part of the choice made by Abraham's experienced, God-fearing servant, which illustrates seeking guidance in choosing a marriage partner, and the marriage that followed is a tender picture of domestic happiness. Abraham's care in guiding Isaac's affections toward a suitable companion through his servant shows that parents should guide their children's affections toward suitable companions. That parental guidance was the fruit of educating Isaac to love a life of noble obedience, and it means parents are to command their households, instruct their children to yield to and respect parental authority, and feel responsibility to direct their sons' and daughters' affections to persons judged suitable rather than leaving affections unguided and unrestrained, because the affections of the young are to a great extent controlled by Satan.
Isaac trusted God to direct the choice of his wife and submitted to having the choice made through his father's God-fearing servant under his father's arrangement. His conduct is an example for children, especially those who profess to fear God, to seek God's direction and respect their parents' judgment in choosing a spouse. His example is held up for children, especially those who profess to fear God, to approach marriage choices in the fear of God and to make them a subject of prayer.
