Judges 7:12

7:12 Now the Midianites, Amalekites, and the people from the east covered the valley like a swarm of locusts. ¹  Their camels could not be counted; they were as innumerable as the sand on the seashore.

Judges 8:10

8:10 Now Zebah and Zalmunna were in Karkor with their armies. There were about fifteen thousand survivors from the army of the eastern peoples; a hundred and twenty thousand sword-wielding soldiers had been killed. ² 

Jeremiah 46:23

46:23 The population of Egypt is like a vast, impenetrable forest.

But I, the Lord, affirm ³  that the enemy will cut them down.

For those who chop them down will be more numerous than locusts.

They will be too numerous to count. ⁴ 

[7:12]  ¹ tn Heb “Midian, Amalek, and the sons of the east were falling in the valley like locusts in great number.”

[8:10]  ² tn Heb “About fifteen thousand [in number] were all the ones remaining from the army of the sons of the east. The fallen ones were a hundred and twenty thousand [in number], men drawing the sword.”

[46:23]  ³ tn Heb “Oracle of the Lord.” Again the first person is adopted because the Lord is speaking and the indirect quotation is used to avoid an embedded quotation with quotation marks on either side.

[46:23]  ⁴ tn The precise meaning of this verse is uncertain. The Hebrew text reads: “They [those who enter in great force] will cut down her forest, oracle of the Lord, though it [the forest] cannot be searched out/through for they [those who come in great force] are more numerous than locusts and there is no number to them.” Some see the reference to the forest as metaphorical of Egypt’s population which the Babylonian army decimates (H. Freedman, Jeremiah [SoBB], 298, and see BDB 420 s.v. I יַעַר 1.a which refers to the forest as a figure of foes to be cut down and destroyed and compare Isa 10:34). Others see the reference to literal trees and see the decimation of Egypt in general (C. von Orelli, Jeremiah, 329). And some see it as a continuation of the simile of the snake fleeing, the soldiers cutting down the trees because they cannot find it (J. A. Thompson, Jeremiah [NICOT], 693). However, the simile of v. 22a has already been dropped in v. 22b-d; they come against her. Hence it is probably best to see this as a continuation of the simile in v. 22c-d and see the reference to the Babylonian army coming against her, i.e., Egypt (the nation or people of Egypt), like woodcutters cutting down trees.
