Job 3:13

“For now should I have lain still, and been quiet, etc.] Signifying, that if the above had been his case, if he had died as soon as born, or quickly after, then he would have been laid in the grave, where he would have lain as still as on a bed; for such is the grave to dead bodies as a bed is to those that lie down and sleep upon it; a place of ease and quiet, where there is freedom from all care and thought, from all trouble, anxiety, and distress; nay, more so than on a bed, where there is often tossing to and fro, and great disquietude, but none to the body in the grave, that is still and silent, where there is no uneasiness nor disturbance, (see <181713>Job 17:13 <235702> Isaiah 57:2); I…”

I should have lain still - - שׁכב shâkab. I should have been “lying down,” as one does who is taking grateful repose. This is a…”

“then had I been at rest: Ecc 6:3-5, Ecc 9:10 Job 3:14”

“13 So should I now have lain and had quiet, I should have slept, then it would have been well with me, 14 With kings and councillors of the earth, Who built ruins for themselves, 15 Or with princes possessing gold, Who filled their houses with silver: 16 Or like a hidden untimely birth I had not been, And as children that have never seen the light. The perf. and interchanging fut. have the signification of oriental imperfecta conjunctivi, according to Ges. 126, 5; עתּה כּי is the usual expression after hypothetical clauses, and takes the perf. if the preceding clause specifies a condition which has not occurred in the past ( Gen 31:42; Gen 43:10; Num 22:29, Num 22:33; Sa1 14:30), the fut. if…”
