Jeremias 17:11

As the partridge sitteth on eggs... — Better, following the LXX. and Vulg., and the marginal reading of the Authorised Version, heaps up eggs and hath not laid them. The words point to a popular belief among the Jews that the partridge steals the eggs of other birds and adds them to her own, with the result that when the eggs are hatched the broods desert her (see Bibl. Educ. iii. p. 73). It thus became a parable of the covetous man, whose avarice leads him to pile up riches which are not rightly his, and which after a while “make to themselves wings” and are seen no more. Modern naturalists have not observed this habit, but it is probable that the belief originated in the practice of the cuckoo laying its eggs in the nest of the partridge, as in that of other birds. The cuckoo (Levítico 11:16; Deuteronômio 14:15) was and is a common bird in Palestine (Bibl. Educ. 2 p. 363).

Shall leave them in the midst of his days. — If we retain the rendering of the Authorised Version the words may refer to the practice of hunting the partridge by driving it from its nest and then striking it with a club (see Bibl. Educ. iii. p. 73). Many commentators, however, adopt the rendering, they (the riches) shall leave him. As covetousness was the besetting sin of Jehoiakim (Jeremias 22:17), the prediction may have pointed specially to him.
