Job 3:6

“As [for] that night, etc.] The night of conception; Job imprecated evils on the day he was born, now on the night he was conceived in, the returns of it: let darkness seize upon it; let it not only he deprived of the light of the moon and stars, but let an horrible darkness seize upon it, that it may be an uncommon and a terrible one: let it not be joined unto the days of the year; the solar year, and make one of them; or, “let it not be one among them” f102, let it come into no account, and when it is sought for, let it not appear, but be found wanting; “or let it not joy” or “rejoice among the days of the year” f103, as Jarchi, Aben Ezra, and others interpret it, or be a joyful one, or…”

“seize upon it--as its prey, that is, utterly dissolve it. joined unto the days of the year--rather, by poetic personification, "Let it not rejoice in the circle of days and nights and months, which form the circle of years."”

“As for “that night.” Job, having cursed the day, proceeds to utter a malediction on the “night” also; see Job 3:3. This malediction extends to Job 3:9. Let darkness seize upon it - Hebrew, Let it take it. Let deep and horrid darkness seize it as its own. Let no star arise upon it; let it be unbroken and uninterrupted gloom. The word “darkness,” however, does not quite express the force of the original. The word used here אפל 'ôphel is poetic, and denotes darkness more intense than is denoted by the word which is usually rendered “darkness” השׁך chôshek. It is a darkness accompanied with clouds and with a tempest. Herder understands it as meaning, that darkness should seize upon that night…”

“Darkness - Constant and extraordinary darkness, without the least glimmering of light from the moon or stars. Be joined - Reckoned as one, or a part of one of them. Job 3:8”

“let it not be joined unto the days: or, let it not rejoice among the days Job 3:7”

“6 That night! let darkness seize upon it; Let it not rejoice among the days of the year; Let it not come into the number of the month. 7 Lo! let that night become barren; Let no sound of gladness come to it. 8 Let those who curse the day curse it, Who are skilled in stirring up leviathan. 9 Let the stars of its early twilight be darkened; Let it long for light and there be none; And let it not refresh itself with eyelids of the dawn. Darkness is so to seize it, and so completely swallow it up, that it shall not be possible for it to pass into the light of day. It is not to become a day, to be reckoned as belonging to the days of the year and rejoice in the light thereof. יחדּ, for יחדּ, fut.…”
