Jeremiah compares the tents of the besiegers on guard round Jerusalem to the booths erected by shepherds or farmers for the protection of their flocks or produce.

As keepers of a field - In the eastern countries grain is often sown in the open country; and, when nearly ripe, guards are placed at different distances round about it to preserve it from being plundered. Jerusalem was watched, like one of these fields, by guards all round about it; so that none could enter to give assistance, and none who wished to escape were permitted to go out.

As keepers of a field, are they against her round about,.... As those that are set to watch a field, in which are fruit and corn of any sort, that thieves and robbers, and wild beasts, may not enter to waste and destroy, and are placed on all sides for that purpose; so the Chaldeans were round about Jerusalem, that none could make their escape out of it; see 2 Kings 25:4,

because she hath been rebellious against me, saith the Lord; it was not without reason that the Lord suffered the Chaldeans to come against Jerusalem, besiege, and take it; the inhabitants of it had rebelled against him, their King and their God; and therefore he delivers them up into the hands of another lord, and a cruel one; they had provoked him to anger with their sins, and caused him to stir up his wrath against them in this way: rebellion against a prince, or against a parent, is a provoking sin; see 1 Samuel 15:23.

As keepers of a {p} field, they are against her on all sides; because she hath been rebellious against me, saith the LORD.

(p) Who keep the fruits so straitly, that nothing can come in or out so would the Babylonians compass Judah.,

4:17 As keepers - They will watch that none relieve them, and that none get out to escape.

17. keepers of a field-metaphor from those who watch a field, to frighten away the wild beasts.

4:5-18 The fierce conqueror of the neighbouring nations was to make Judah desolate. The prophet was afflicted to see the people lulled into security by false prophets. The approach of the enemy is described. Some attention was paid in Jerusalem to outward reformation; but it was necessary that their hearts should be washed, in the exercise of true repentance and faith, from the love and pollution of sin. When lesser calamities do not rouse sinners and reform nations, sentence will be given against them. The Lord's voice declares that misery is approaching, especially against wicked professors of the gospel; when it overtakes them, it will be plainly seen that the fruit of wickedness is bitter, and the end is fatal.
