▼tn The term חֶסֶד (khesed) can mean “mercy, loyal love, covenant love.” The two words חֶסֶד וֶאֱמֶת (khesed veʾemet, “mercy and truth”) are used together over two dozen times. Sometimes they are treated in parallel clauses and sometimes they are paired in a hendiadys, to be understood as “faithful mercy.” Here they are pictured as concrete objects to tie around one’s neck, so at that level they are distinct even though they complement each other.

▼sn The picture of tying mercy and truth on the neck (also at 6:21) is similar to tying God’s commands on the hand or letting them be frontlets for the eyes (Deut 6:8; 11:18). To live by these characteristics is compared to wearing them like clothes, to have these qualities adorn the “wearer.” The picture of writing them on the heart emphasizes the inward appropriation of the teachings as a complement to their outward manifestation.
