[12:6] 1 sn The pennies refer to the assarion, a small Roman copper coin. One of them was worth one sixteenth of a denarius or less than a half hour’s average wage. Sparrows were the cheapest thing sold in the market. God knows about even the most financially insignificant things; see Isa 49:15.
[12:7] 2 sn Do not be afraid. One should respect and show reverence to God (v. 5), but need not fear his tender care.
