Deuteronomy 24:21
19 Whenever you reap your harvest in your field and leave some unraked grain there, you must not return to get it; it should go to the resident foreigner, orphan, and widow so that the Lord your God may bless all the work you do. 20 When you beat your olive tree you must not repeat the procedure; the remaining olives belong to the resident foreigner, orphan, and widow. 21 When you gather the grapes of your vineyard you must not do so a second time; they should go to the resident foreigner, orphan, and widow. 22 Remember that you were slaves in the land of Egypt; therefore, I am commanding you to do all this.
Jeremiah 49:9
7 The Lord of Heaven’s Armies spoke about Edom: “Is wisdom no longer to be found in Teman? Can Edom’s counselors not give her any good advice? Has all their wisdom turned bad? 8 Turn and flee! Take up refuge in remote places, you people who live in Dedan. For I will bring disaster on the descendants of Esau. I have decided it is time for me to punish them. 9 If grape pickers came to pick your grapes, would they not leave a few grapes behind? If robbers came at night, would they not pillage only what they needed? 10 But I will strip everything away from Esau’s descendants. I will uncover their hiding places so they cannot hide. Their children, relatives, and neighbors will all be destroyed. Not one of them will be left! 11 Leave your orphans behind, and I will keep them alive. Your widows, too, can depend on me.”
Notes and References
"... There are a few usages that suggest the Holiness Code: in Jeremiah 2:7 we read, "my heritage you made loathsome"; one recalls the repetition in Leviticus 18:22-30. Again Jeremiah 6:9 contradicts the law on gleaning in Leviticus 19:9-10, but it is more likely to reflect the form of the law in Deuteronomy 24:21. Jeremiah 9:3 may well have the sequence of laws in Leviticus 19:16-18 in mind: the verse in Jeremiah associates 'neighbor,' 'brother,' and 'slanderer,' offering a picture of the breakdown of covenant solidarity; Leviticus 19:16 forbids going around as a slanderer and mentions 'neighbor,' and verses 17-18 state that one should not hate one's brother and should love one's neighbor as oneself. Finally, 'your burnt offerings are not acceptable, nor are your sacrifices pleasing to me' (Jeremiah 6:20) suggests an antecedent Leviticus 22:20, 'You shall not offer anything that has a blemish, for it will not be acceptable for you.' My conclusion is that it is possible, though not proven, that phrases of Jeremiah's reflect the Holiness Code. In addition, there are phrases at the end of Leviticus 26 that imply the experience of the fall of Jerusalem in 587 and the consequent exile and some of these phrases appear to be borrowed from Jeremiah: the striking image of the corpses of idols (Leviticus 26:30) is doubtless drawn from Jeremiah 16:18, and the image of the uncircumcised heart (Leviticus 26:41) may be dependent on that in Jeremiah 4:4 ..."
