Genesis 49:3 אוֹנִ֑י manly vigor my

Reuben, you are my firstborn, my might, and the beginning of my strength, excelling in honor, excelling in power.

Here: 'My vigor,' especially the power to father children. The same phrase, 'the first fruit of his vigor', defines the firstborn in Deuteronomy 21:17 and the firstborn of Egypt in Psalms 78:51 and 105:36.

Deuteronomy 21:17 אֹנ֔וֹ manly vigor his

Instead, he must acknowledge the firstborn, the son of his unloved wife, by giving him a double portion of all that he has. For that son is the firstfruits of his father’s strength; the right of the firstborn belongs to him.

Job 18:7 אוֹנ֑וֹ vigor his

His vigorous stride is shortened, and his own schemes trip him up.

Job 18:12 אֹנ֑וֹ trouble his

His strength is depleted, and calamity is ready at his side.

Job 20:10 אוֹנֽוֹ׃ wealth his

His sons will seek the favor of the poor, for his own hands must return his wealth.

Job 40:16 וְ֝אֹנ֗וֹ and power its

See the strength of his loins and the power in the muscles of his belly.

Psalm 78:51 א֝וֹנִ֗ים manly vigor<s>

He struck all the firstborn of Egypt, the virility in the tents of Ham.

Here: A man's life-force, especially his power to father children. 'The first of their vigor' is a fixed phrase for a man's first son (Genesis 49:3; Deuteronomy 21:17). The plural adds intensity: their full manly vigor. It does not mean military strength or rulers.

Psalm 105:36 אוֹנָֽם׃ manly vigor their

Then He struck all the firstborn in their land, the firstfruits of all their vigor.

Here: 'Their vigor', meaning above all a man's power to father children. Together with re'shit it forms a set idiom for the firstborn son (Gen 49:3; Deut 21:17). It is not military or muscular strength.

Proverbs 11:7 אוֹנִ֣ים strength<s>

When the wicked man dies, his hope perishes, and the hope of his strength vanishes.

Here: As the vowels stand, the plural of ʾôn: "(great) strength, power, resources, wealth." "Expectation of strength" means what he expected his power and means to get him, or the hope he placed in them. Some read it as "evildoers" instead (see debates).

Isaiah 40:26 אוֹנִים֙ strength<s>

Lift up your eyes on high: Who created all these? He leads forth the starry host by number; He calls each one by name. Because of His great power and mighty strength, not one of them is missing.

Here: 'Strengths' (plural, meaning 'great vigour'). This is the exact word repeated in 40:29, where God gives strength to 'the one who has no strength'. The power that keeps the stars in place is the power God offers the weary.

Isaiah 40:29 אוֹנִ֖ים [is] power<s>

He gives power to the faint and increases the strength of the weak.

Here: Vigour, the strength of a body in its prime. Elsewhere it is used of a man's vitality and fathering power. The plural form stresses how full that strength is. In 40:26 God's 'abundance of vigour' (the same word) is why not one star goes missing.

Hosea 12:3 וּבְאוֹנ֖וֹ and in manly vigor his

In the womb he grasped his brother’s heel, and in his vigor he wrestled with God.

Here: "And in his vigor": the full strength of a grown man, the strength to father children (Genesis 49:3; Deuteronomy 21:17). Set against "womb", it also means "once he was grown". The same word comes back in 12:8, where Ephraim boasts "I have found wealth (ʾôn) for myself".

Hosea 12:8 א֖וֹן wealth

And Ephraim boasts: “How rich I have become! I have found wealth for myself. In all my labors, they can find in me no iniquity that is sinful.”

Here: Wealth as 'strength' or resources. The same word was used of Jacob's strength when he wrestled God (v. 3). It also sounds like ʿāwōn ('iniquity') later in the verse, a pun the hearer would catch.
