25 Heb “at your end.”
26 The form is the perfect tense with the vav consecutive; it is equal to a specific future within this context. The verb means “to growl, groan.” It refers to a lion when it devours its prey, and to a sufferer in pain or remorse (e.g., Ezek 24:23).
27 Heb “in the finishing of your flesh and your body.” The construction uses the Qal infinitive construct of כָּלָה (calah) in a temporal clause; the verb means “be complete, at an end, finished, spent.”
28 The vav that introduces this clause functions in an explanatory sense.
29 The Hebrew term מוֹרַי (moray) is the nominal form based on the Hiphil plural participle with a suffix, from the root יָרָה (yarah). The verb is “to teach,” the common noun is “instruction, law [torah],” and this participle form is teacher (“my teachers”).
30 The idioms are vivid: This expression is “incline the ear”; earlier in the first line is “listen to the voice,” meaning “obey.” Such detailed description emphasizes the importance of the material.
31 The form is the Piel plural participle of לָמַד (lamad) used substantivally.

and at the end of your life you groan,

when your flesh and body are consumed,

and you say, “How I hated discipline,

and my heart despised reproof!

I did not listen to the voice of my teachers

or incline my ear to my instructors.

At the end of your life you will groan,

when your flesh and body are spent.

You will say, “How I hated discipline!

How my heart spurned correction!

I would not obey my teachers

or turn my ear to my instructors.

At the end of your life, you will lament

when your physical body has been consumed,

and you will say, “How I hated discipline,

and how my heart despised correction.

I didn’t obey my teachers

or listen closely to my instructors.

In the end you will groan in anguish

when disease consumes your body.

You will say, “How I hated discipline!

If only I had not ignored all the warnings!

Oh, why didn’t I listen to my teachers?

Why didn’t I pay attention to my instructors?

and you groan at your end,

when your flesh and body are consumed,

and say “How I hated discipline,

and I despised reproof!”

and “I did not listen to the voice of my teachers,

and I did not incline my ear to my instructors!

And thou mourn at the last,

When thy flesh and thy body are consumed,

And say, How have I hated instruction,

And my heart despised reproof;

And have not obeyed the voice of my teachers,

Nor inclined mine ear to them that instructed me!
