If your children will keep my covenant and my testimony that I shall teach them, their children shall also sit upon your throne forevermore.

12. What then? "The Lord hath made a faithful oath unto David, and He shall not shrink from it; Of the fruit of thy body shall I set upon thy seat. If thy children will keep My covenant and My testimonies that I shall learn them, their children also shall sit upon thy seat for evermore" (ver. 12). If thy children keep My covenant, their children also shall sit for evermore. The parents establish a desert on behalf of their children. What if his children should keep the covenant, and their children should not keep it? Why is the happiness of the children promised in relation to their parents' deservings? For what saith He, "If thy children will keep My covenant, their children also shall sit for evermore"-He saith not, if thy children keep My covenant, they shall sit upon thy seat; and if their children keep My covenant, they also shall sit upon thy seat: but he saith, "If thy children keep My covenant, their children also shall sit upon thy seat for evermore"-except because He here wished their fruit to be understood by their children? "If thy children," He saith, "will keep My covenant, and if thy children shall keep My testimonies that I shall learn them; their children also shall sit upon thy seat:" that is, this will be their fruit, that they sit upon thy seat. For in this life, brethren, do all of us who labour in Christ, all of us who tremble at His words, who in any way endeavour to execute His will, and groan while we pray His help that we may fulfil what He commandeth; do we already sit in those seats of bliss which are promised us? No: but holding His commandments, we hope this will come to pass. This hope is spoken of under the figure of sons; because sons are the hope of man living in this life, sons are his fruit. For this reason also men, when excusing their avarice, allege that they are reserving for their children what they hoard up; and, unwilling to give to the destitute, excuse themselves under the name of piety, because their children are their hope. For all men who live according to this world, declare it to be their hope, to be fathers of children they may leave behind them. Thus then He describes hope generally under the name of children, and saith, "If thy children will keep My covenant and My testimonies that I shall learn them, their children also shall sit upon thy seat for evermore:" that is, they shall have such fruits, that their hope shall not deceive them, that they may come there where they hope to come. At present therefore they are as fathers, men of hope for the future; but when they have attained what they hope, they are children; because they have brought forth and produced in their works that which they gain. And this is preserved unto them for the future, because futurity itself commonly signifieth children.
13. Or if thou understand actual men to be meant by children, the words, "If thy children will keep My covenant and My testimonies that I shall teach them," may mean, "If thy children will keep My covenant and testimonies that I shall teach them, and their children also;" that is, if they too keep My covenant; so that here thou must make a slight pause, and then infer that "they shall sit upon thy seat for evermore;" that is, both thy children and their children, but all if they keep My covenant. What then, if they keep it not? Hath the promise of God failed? No: but it is said and promised for this reason, that God foresaw: what, save that they would believe? But that no man should as it were threaten God's promises, and prefer to place in his own power the fulfilment of what God promised: for this reason he saith, "He made an oath:" whereby he showeth that it will without doubt take place. How then hath He said here, "If they will keep My covenant"? Glory not in the promises, and leave out thy failing to keep the covenant. Then wilt thou be the son of David, if thou shalt keep the covenant; but if thou dost not keep it, thou wilt not be David's son. God promised to the sons of David. Say not, I am David's son if thou degenerate. If the Jews, who were born of this very stock, say not this (nay, they say it, but they are under a delusion. For the Lord saith openly, "If ye were Abraham's children, ye would do the works of Abraham." He thereby denied them to be children, because they did not the works), how do we call ourselves David's children, who are not of his race according to the flesh? It follows then that we are not children, save by imitating his faith, save by worshipping God, as he worshipped. If therefore what thou hopest not through descent, thou wilt not endeavour to obtain by works; how shall the sitting upon David's seat be fulfilled in thee? And if it shall not be fulfilled in thee, thinkest thou that it shall not be fulfilled at all? And how hath He found it in the woodland tracts? and how did His feet stand? Whatsoever then thou mayest be, that house will stand.
