Jonah 2:8

“They that observe lying vanities forsake their own mercy.] They that worship idols, who are nothing, mere vanity and lies, and deceive those that serve them, these forsake the God of their lives, and of their mercies; and so do all such who serve divers lusts and pleasures, and pursue the vanities of this life; and also those who follow the dictates of carnal sense and reason, to the neglect of the will of God, and obedience to his commands; which was Jonah’s case, and is, I think, chiefly intended. The Targum, Syriac version, and so Jarchi, and most interpreters, understand it of worshippers of idols in general; and Kimchi of the mariners of the ship Jonah had been in; who promised to…”

“observe lying vanities--regard or reverence idols, powerless to save (). mercy--Jehovah, the very idea of whom is identified now in Jonah's mind with mercy and loving-kindness. As the Psalmist () styles Him, "my goodness"; God who is to me all beneficence. Compare , "the God of my mercy," literally, "my kindness-God." Jonah had "forsaken His own mercy," God, to flee to heathen lands where "lying vanities" (idols) were worshipped. But now, taught by his own preservation in conscious life in the fish's belly, and by the inability of the mariners idols to lull the storm (), estrangement from God seems estrangement from his own happiness (; ). Prayer has been restrained in Jonah's case, so that…”

“They that observe lying vanities - , i. e., (by the force of the Hebrew form , that diligently watch, pay deference to, court, sue, “vanities of vanities,” vain things, which prove themselves vain at last, failing the hopes which trust in them. Such were actual idols, in which men openly professed that they trusted Such are all things in which men trust, out of God. One is not more vain than another. All have this common principle of vanity, that people look, out of God, to that which has its only existence or permanence from God. It is then one general maxim, including all people’s idols, idols of the flesh, idols of intellect, idols of ambition, idols of pride, idols of self and self-will.…”

“They - Whoever they are that depend upon idols. Mercy - The Lord, who is to all that depend upon him, the fountain of living waters; who is an eternal fountain of mercy, and flows freely to all that wait for him. Jonah 2:9”

“2:8-9 The conclusion to Jonah’s psalm-prayer bears similarity to 1:16: The sailors also responded to the Lord’s power to save and acts of mercy with sacrifices and vows.”

“Sa1 12:21; Kg2 17:15; Psa 31:6; Jer 2:13, Jer 10:8, Jer 10:14, Jer 10:15, Jer 16:19; Hab 2:18-20 Jonah 2:9”

“8 They who hold to false vanities Forsake their own mercy. 9 But I will sacrifice to Thee with the call of thanksgiving. I will pay what I have vowed. Salvation is with Jehovah. In order to express the thought emphatically, that salvation and deliverance are only to be hoped for from Jehovah the living God, Jonah points to the idolaters, who forfeit their mercy. משׁמּרים הבלי־שׁוא is a reminiscence of Psa 31:7. הבלי־שׁוא, worthless vanities, are all things which man makes into idols or objects of trust. הבלים are, according to Deu 32:21, false gods or idols. Shâmar, to keep, or, when applied to false gods, to keep to them or reverence them; in Hos 4:10 it is also applied to Jehovah. חסדּם…”
