Psalms 139:8

“If I ascend up into heaven, thou [art] there, etc.] No man hath ascended or can ascend to heaven of himself; it is an hyperbolical expression, as are those that follow; none but Christ has ascended to heaven by his own power, who descended from it; saints hope to go there at death, and, when they do, they find God there; that is his habitation, his throne is there, yea, that is his throne; here he keeps court and has his attendants, and here he will be seen and enjoyed by his people to all eternity; if I make my bed in hell, behold, thou [art there]; which, if understood of the place of the damned, is a place of torment, and a very unfit one to make a bed in, being a lake burning with fire…”

“If I ascend up into heaven - The word “heaven” here, in the original is in the plural number - “heavens,” - and includes all that there is above the earth - the highest worlds. If I make my bed - Properly, “If I strew or spread my couch.” If I should seek that as the place where to lie down. In hell - Hebrew, “Sheol.” See the notes at Isaiah 14:9, where the word is fully explained. The word here refers to the under-world - the abodes of the dead; and, in the apprehension of the psalmist, corresponds in depth with the word “heaven” in height.

“The future form אסּק, customary in the Aramaic, may be derived just as well from סלק (סלק), by means of the same mode of assimilation as in יסּב = יסבּב, as from נסק (נסק), which latter is certainly only insecurely established by Dan 6:24, להנסקה (cf. להנזקת, Ezr 4:22; הנפּק, Dan 5:2), since the Nun, as in להנעלה, Dan 4:3, can also be a compensation for the resolved doubling (vid., Bernstein in the Lexicon Chrestom. Kirschianae, and Levy s.v. נסק). אם with the simple future is followed by cohortatives (vid., on Psa 73:16) with the equivalent אשּׂא among them: et si stratum facerem (mihi) infernum (accusative of the object as in Isa 58:5), etc. In other passages the wings of the sun ( Mal…”
