17:1-2 The Lord directed Ezekiel to present a riddle (Heb. hidah, allegory, enigmatic saying) and a parable (Heb. mashal, proverb, comparison) to his audience of Jewish exiles.
"It is a riddle in that its meaning needs to be explained; there is a deeper meaning which underlies the figurative form, for something in its presentation is obscure. It is a parable in that it is an allegory."246
"A riddle' . . . was commonly used in international politics between kings . . . If one failed to answer the riddle of the other, he might be called on to submit to him as a vassal. In some cases he might even be put to death."247
The purpose for using riddles was apparently to test the intelligence or cleverness of the hearer (cf. Judg. 14:12-19; 1 Kings 10:1; 2 Chron. 9:1; Matt. 13).248
"This allegory differs from others Ezekiel was commanded to tell his audience because of its opaqueness, so he was to tell it as a riddle (v. 2)."249
17:3-6 In this riddle, a powerful and impressive eagle came to Lebanon, cropped off the top of one of its famous cedar trees, and carried these twigs to a land of merchants and a city of traders. This eagle also took some of the seed from Lebanon and planted it in fertile soil near a body of water so it would flourish, like a willow tree (cf. Isa. 44:4). This seed sprouted and became a low, spreading vine (cf. 15:1-8) that sent out branches upward toward the eagle and roots downward.
Lebanon was an alternative name for the land of Canaan that emphasized its great beauty and fruitfulness (cf. Josh. 1:4; 2 Kings 14:9). The Lord evidently used it here because He wanted to develop the idea of a bird plucking the top off a tree, and this was more typical in Lebanon than in Israel because of Lebanon's many cedar trees.
17:7-8 Another large eagle, not quite as glorious as the first, came along. The vine reached out with its branches and roots toward it so this eagle might water it. The vine did this even though it was growing in good soil with abundant water nearby, enough to make it a luxuriant and fruitful plant.
17:9-10 The Lord asked if the owner of such a vine would not pull it out of its soil and cause it to wither and become unfruitful. Nothing that anyone could do could cause such a vine to recover its original health and fruitfulness after such treatment (cf. vv. 22-24). Even though its roots were still in the ground it would not thrive. The hot east wind would easily wither it where it grew (cf. 19:12; Job 27:12; Isa. 27:8; Hos. 13:15).
