Testament of Levi 13:6
Testament of the Twelve PatriarchsAnd do ye also teach your children letters, That they may have understanding all their life, Reading unceasingly the law of God. For every one that knoweth the law of the Lord shall be honoured, And shall not be a stranger whithersoever he goeth. Yea, many friends shall he gain more than his parents, And many men shall desire to serve him, And to hear the law from his mouth. Work righteousness, therefore, my children, upon the earth, That ye may have (it) as a treasure in heaven. And sow good things in your souls, That ye may find them in your life. But if ye sow evil things, Ye shall reap every trouble and affliction. Get wisdom in the fear of God with diligence; For though there be a leading into captivity, And cities and lands be destroyed, And gold and silver and every possession perish, The wisdom of the wise nought can take away, Save the blindness of ungodliness, and the callousness (that comes) of sin.
Galatians 6:7
4 Let each one examine his own work. Then he can take pride in himself and not compare himself with someone else. 5 For each one will carry his own load. 6 Now the one who receives instruction in the word must share all good things with the one who teaches it. 7 Do not be deceived. God will not be made a fool. For a person will reap what he sows, 8 because the person who sows to his own flesh will reap corruption from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit. 9 So we must not grow weary in doing good, for in due time we will reap, if we do not give up. 10 So then, whenever we have an opportunity, let us do good to all people, and especially to those who belong to the family of faith.
Notes and References
"... The harvest of what is good is here associated with the epoch immediately after the end of the present evil age (compare 1:4), resulting in a golden future (compare the eschatological epoch of the Spirit) far surpassing the previous harvest of evil. This symbolic association of the ‘sowing’ of a ‘good seed’ with the apocalyptic fullness of time is also expressed in the Syriac Apocalypse of Baruch: “Behold! The days come and it shall be when the time of the age has ripened, and the harvest of its evil and good seed has come, That the Mighty One will bring upon the earth and its inhabitants and upon its rulers perturbation of spirit and stupor of heart” (2 Baruch 70:2). In Testament of Levi 13.6 the author admonishes that the sowing of good things in the soul brings a harvest of good things; that the sowing of evil brings a harvest of trouble and tribulation. Both concepts bear close resemblance to Paul’s mention regarding sowing to Spirit and reaping eternal life in contrast to sowing of the flesh and reaping destruction (6:8) ..."
