Proverbs 6:21

6:21 Bind them ¹  on your heart continually;

fasten them around your neck.

Proverbs 7:3

7:3 Bind them on your forearm; ² 

write them on the tablet of your heart. ³ 

Proverbs 3:3

3:3 Do not let truth and mercy ⁴  leave you;

bind them around your neck,

write them on the tablet of your heart. ⁵ 

[6:21]  ¹ sn The figures used here are hypocatastases (implied comparisons). There may also be an allusion to Deut 6 where the people were told to bind the law on their foreheads and arms. The point here is that the disciple will never be without these instructions. See further, P. W. Skehan, Studies in Israelite Poetry and Wisdom (CBQMS), 1-8.

[7:3]  ² tn Heb “fingers” (so KJV and many other English versions). In light of Deut 6:8, “fingers” appears to be a metonymy for the lower part of the arm.

[7:3]  ³ sn This is an allusion to Deut 6:8. Binding the teachings on the fingers and writing them on the tablets here are implied comparisons for preserving the teaching in memory so that it can be recalled and used with ease.

[3:3]  ³ tn The two words חֶסֶד וֶאֶמֶת (khesed ve’emet, “mercy and truth”) form a nominal hendiadys, the second word becoming an adjective: “faithful covenant love” or “loyal [covenant] love and faithfulness.”

[3:3]  ⁴ sn This involves two implied comparisons (hypocatastasis). One is a comparison of living out the duties and responsibilities taught with binding a chain around the neck, and the other is a comparison of the inward appropriation of the teachings with writing them on a tablet. So the teachings are not only to become the lifestyle of the disciple but his very nature.
