In Job 1:4-5 , it mentions that Job's children would often have feasts in order to celebrate.

Job 1:1-8

1 There was a man in the land of Uz whose name was Job; and that man was blameless, upright, fearing God and turning away from evil...more...scripture....4 His sons used to go and hold a feast in the house of each one on his day, and they would send and invite their three sisters to eat and drink with them. 5 When the days of feasting had completed their cycle, Job would send and consecrate them, rising up early in the morning and offering burnt offerings according to the number of them all; for Job said, “Perhaps my sons have sinned and cursed God in their hearts.” Thus Job did continually...more...scripture....8 The Lord said to Satan, “Have you [c]considered My servant Job? For there is no one like him on the earth, a blameless and upright man, [d]fearing God and turning away from evil.” ......

1 אִ֛ישׁ הָיָ֥ה בְאֶֽרֶץ־ע֖וּץ אִיּ֣וֹב שְׁמ֑וֹ וְהָיָ֣ה׀ הָאִ֣ישׁ הַה֗וּא תָּ֧ם וְיָשָׁ֛ר וִירֵ֥א אֱלֹהִ֖ים וְסָ֥ר מֵרָֽע׃

Job 1:5 indicates that Job would offer burnt offerings as an act of propitiation/expiation/atonement for his children's "probable/possible" sins:

Job 1:5

5 When the days of feasting had completed their cycle, Job would send and consecrate them, rising up early in the morning and offering burnt offerings according to the number of them all; for Job said, “Perhaps my sons have sinned and cursed God in their hearts.” Thus Job did continually

I use the words "probable/possible" sins of the children because Job himself uses the says "Perhaps my sons sinned and cursed God..."

Job 1:5b

.......“Perhaps my sons have sinned and cursed God in their hearts.” Thus Job did continually....

However, Job offers sacrifices in a frequent and routine manner. These sacrifices were made by Job in order to propitiate/expiate/atone for sins that to Job's knowledge his children may or may Not of committed. Therefore, Job's offering of said sacrifices for sins that may Or may Not have happened seem to be legalistic.

A Godly person Only repents and makes atonement for a sin after she/he genuinely and sincerely accepts that she/he has committed said sin.

However, when Job says the following by using the word "Perhaps", it seems like he is just offering sacrifices in case his children did sin (Essentially, it makes offering sacrifices:

-seem like a routine, frequent & trivial business transaction( or purchasing some kind of insurance policy )

-as opposed to viewing the offering of sacrifices as a deeply mental & spiritual & emotional & intimate interaction that we human sinners have with God in order to atone for our sins ):

Job 1:5b

.......“Perhaps my sons have sinned and cursed God in their hearts.” Thus Job did continually....

Most of the commentaries on https://biblehub.com/commentaries/job/1-5.htm
seem to give credit to Job for his act of offering burnt offerings in order to propitiate/expiate/atone for his children's sins.

However, I'm Not really all that satisfied with the said commentaries on biblehub.com because Job himself says to himself:

Job 1:5b

.......“Perhaps my sons have sinned and cursed God in their hearts.” Thus Job did continually....

To me, the aforementioned verse seems to suggest that Job is legalistic because he says "perhaps" his children sinned and cursed God. It seems like Job is offering his sacrifices in a perfunctory and legalistic mechanical manner.

Could someone please provide their insight/interpretation/exegesis of said bible passage?
