רִיק

Leviticus 26:16 לָרִיק֙ to <the> emptiness

then this is what I will do to you: I will bring upon you sudden terror, wasting disease, and fever that will destroy your sight and drain your life. You will sow your seed in vain, because your enemies will eat it.

Here: 'For emptiness', meaning for nothing. All the farmer's labour comes to nothing.

Leviticus 26:20 לָרִ֖יק to <the> emptiness

and your strength will be spent in vain. For your land will not yield its produce, and the trees of the land will not bear their fruit.

Here: 'For emptiness', meaning for nothing at all. The word pictures an empty container: all the effort goes in and nothing comes back out.

Job 39:16 לְרִ֖יק [is] to emptiness

She treats her young harshly, as if not her own, with no concern that her labor was in vain.

Psalm 2:1 רִֽיק׃ vanity

Why do the nations rage and the peoples plot in vain?

Here: Grammatically it is the thing they mutter: they plot 'emptiness', a plan with nothing inside it. It also carries the sense 'for nothing, futilely'. The plan is hollow, and it will come to nothing.

Psalm 4:2 רִ֑יק vanity

How long, O men, will my honor be maligned? How long will you love vanity and seek after lies? Selah

Here: "Emptiness", something hollow with nothing in it. It could mean empty words (baseless accusations) or empty gods (idols). The Masoretic accents put a major pause here, so "you love emptiness" closes the first half of the verse.

Psalm 73:13 רִ֭יק vanity

Surely in vain I have kept my heart pure; in innocence I have washed my hands.

Here: Emptiness, something with nothing inside. Used here as an adverb, "for nothing, to no purpose". The speaker is saying his integrity produced nothing: no reward, no protection.

Isaiah 30:7 וָרִ֖יק and vanity

Egypt’s help is futile and empty; therefore I have called her Rahab Who Sits Still.

Here: Emptiness, like a pot with nothing in it. Paired with hevel it gives 'thin air and nothing', a strong way of saying Egypt's help will come to zero.

Isaiah 49:4 לְרִ֣יק to emptiness

But I said, “I have labored in vain, I have spent My strength in futility and vanity; yet My vindication is with the LORD, and My reward is with My God.”

Here: "For emptiness": work that yields nothing, like a container with nothing in it. It is placed first in the line for emphasis. The same phrase appears in the covenant curse of Leviticus 26:16, 20, where seed is sown and strength is spent "for nothing".

Isaiah 65:23 לָרִ֔יק to <the> emptiness

They will not labor in vain or bear children doomed to disaster; for they will be a people blessed by the LORD—they and their descendants with them.

Here: 'For emptiness': for nothing, with empty hands at the end. It is the stock phrase of the covenant curse in Leviticus 26:16, 20, now cancelled.

Jeremiah 51:34 רִ֔יק emptiness

“Nebuchadnezzar king of Babylon has devoured me; he has crushed me. He has set me aside like an empty vessel; he has swallowed me like a monster; he filled his belly with my delicacies and vomited me out.

Here: 'Of emptiness,' that is, an empty dish. Jerusalem has been scraped clean of everything that filled her.

Jeremiah 51:58 רִ֛יק emptiness

This is what the LORD of Hosts says: “Babylon’s thick walls will be leveled, and her high gates consumed by fire. So the labor of the people will be for nothing; the nations will exhaust themselves to fuel the flames.”

Here: 'Emptiness.' Their labor produces a void. This is the sense of the old English 'in vain', not conceit.

Habakkuk 2:13 רִ֥יק vanity

Is it not indeed from the LORD of Hosts that the labor of the people only feeds the fire, and the nations weary themselves in vain?

Here: Literally 'emptiness', what is left in an empty vessel. The second half of the line says plainly what the fire image implies: the labor yields nothing that lasts.
