Commentary
9 notes on this verseDidst thou know then that thou wast about to be born, and didst thou know the number of thy days? As if He were openly saying, What wonder if thou understandest not thine end, since thou dost not comprehend thy beginning? And since thou knowest not with what beginning thou camest hither, what wonder, if thou canst not tell with what end thou art taken away? If therefore it was My work to bring thee forward from secresy to sight at thy beginning, it will be Mine also to bring thee back from sight to secresy.

the way to the home of light
on Job 38:19-21
Verse 21 turns openly sarcastic, “Surely you know, for you were already born”, since Job's age is nothing beside the ages the question assumes. Henry reads the irony as the chapter's method throughout, each question answerable by God alone and put to the man who has demanded answers.

for you were already born
Barnes allows two readings of the verse, a plain question or keen sarcasm. Clarke hears irony in rabbim, a word for multitudes. Gregory drew from it that a man who does not know his own beginning cannot know his end or the number of his days.

Knowest thou it, because thou wast then born?.... When light and darkness were first separated, and had their several apartments assigned them; their laws and rules given them, and their bounds and limits set them?
How they still keep their turns interchangeably. It is God that makes the outgoings of the morning and of the evening to rejoice ( Ps. lxv. 8 ); for it is his order, and no order of ours, that is executed by the outgoings of the morning light and the darkness of the night.

Knowest thou it, because thou wast then born? - This may either be a question, or it may be spoken ironically. According to the former mode of rendering it, it is the same as asking Job whether he had lived long enough to understand where the abode of light was, or whether he had an existence when it was created, and knew where its home was appointed. According to the latter mode, it is keen sarcasm. “Thou must know all this, for thou art so old.

"What is the way (to the place wherein) light dwelleth?" The origin of light and darkness. In Ge 1:3-5, 14-18, "light" is created distinct from, and previous to, light-emitting bodies, the luminaries of heaven.

Knowest thou - This is another strong and biting irony, and the literal translation proves it: “Thou knowest, because thou was then born; and the number of thy days is great,” or multitudinous, רבים rabbim, multitudes.
