Sparrow

Sparrow - (Easton's Bible Dictionary)

Mentioned among the offerings made by the very poor. Two sparrows were sold for a farthing (Matt. 10:29), and five for two farthings (Luke 12:6). The Hebrew word thus rendered is tsippor, which properly denotes the whole family of small birds which feed on grain (Lev. 14:4; Ps. 84:3; 102:7). The Greek word of the New Testament is strouthion (Matt. 10:29-31), which is thus correctly rendered.

Sparrow - (Webster's 1828 Dictionary)
