Thematic Bible: Ordering the minutest matters

Are not two sparrows sold [in the market for food] for a small coin [Note: The coin mentioned here was worth about a half hour's worth of a farm laborer's pay, or about $3 in 1994]? And not a [single] one of them can fall to the ground without your Father [knowing about it]. God even knows the number of hairs on your head [Note: The average full head of hair has approximately 25,000 hairs].
