Jeremiah 17:9

"The heart is deceitful above all things, and it is exceedingly corrupt: who can know it? I, Jehovah, search the mind, I try the heart, even to give every man according to his ways, according to the fruit of his doings. As the partridge that sitteth on eggs which she hath not laid, so is he that getteth riches and not by right; in the midst of his days they shall leave him, and at his end he shall be a fool."

The question that surfaces here is, if the one who serves God fares so much better in this life than the unrighteous person, why do men then trust the arm of flesh? Barnes attempted an answer to this, saying, "Because man's deceitful heart is incapable of seeing things in a straight-forward manner; it is full of shrewd guile."[14]

Our heart's a soil that breeds

The sweetest flowers or vilest weeds,

Flowers lovely as the morning light,

Or weeds as deadly as the aconite.[15]

The mention here in Jeremiah 17:11 of a partridge setting upon eggs she did not lay derived from, "A popular belief of antiquity, which Jeremiah used to illustrate the truth that riches unlawfully acquired are a precarious possession."[16] Translators usually render this as a statement that the eggs would not hatch; but John Bright in the Anchor Bible rendered it "Like a partridge hatching eggs that it laid not."[17]

The personal experience of this writer and his brother Robert verifies the truth that hatching "strange eggs" can be a terrible mistake for the hatcher!. Robert had a pet hen, named Bob White; we found a hawk's nest and put two of the eggs under Bob White when the hen was setting, and one of the hawk eggs hatched. Our father wanted to kill it, but we insisted on keeping it. Then, one day when we came home from church the young hawk was sitting on the gate post with Bob White's feathers scattered all around! He had eaten his own mother!

The old proverb about the partridge's hatching eggs that she had not laid is not supposed to be true to natural history; but that did not prevent Jeremiah's use of it as an illustration. There is no necessity to charge Jeremiah with believing the saying. Besides that, since the species of bird is not clearly identifiable, there might have been some bird, unknown to us now, of which the old saying was altogether true.

In fact, there was a Dr. Blayney, who thought that the bird here was not a partridge at all; and he translated the passage: "As the kore that hatcheth what it does not lay, So is he that getteth riches, and not according to right."[18]
