Psalms 139:1

1. O Jehovah! thou hast searched me David declares, in the outset of this Psalm, that he does not come before God with any idea of its being possible to succeed by dissimulation, as hypocrites will take advantage of secret refuges to prosecute sinful indulgences, but that he voluntarily lays bare his innermost heart for inspection, as one convinced of the impossibility of deceiving God. It is thine, he says, O God! to discover every secret thought, nor is there anything which can escape thy notice, He then insists upon particulars, to show that his whole life was known to God, who watched him in all his motions — when he slept, when he arose, or when he walked abroad. The word רע, rea, which we have rendered thought, signifies also a friend or companion, on which account some read — thou knowest what is nearest me afar off, a meaning more to the point than any other, if it could be supported by example. The reference would then be very appropriately to the fact that the most distant objects are contemplated as near by God. Some for afar off read beforehand, in which signification the Hebrew word is elsewhere taken, as if he had said — O Lord, every thought which I conceive in my heart is already known to thee beforehand. But I prefer the other meaning, That God is not confined to heaven, indulging in a state of repose, and indifferent to human concerns, according to the Epicurean idea, and that however far off we may be from him, he is never far off from us.

The verb זרה, zarah, means to winnow as well as to compass, so that we may very properly read the third verse — thou winnowest my ways, Piscator, Campensis, Pagninus, Luther, and our English Version, read “thou compassest.” This no doubt gives the meaning, of the original, though not the precise idea, which is noticed on the margin of our English Bible to be “winnowest.” The verb זרה, zarah, employed, signifies to disperse, to fan, to ventilate, to winnow; and here it denotes that as men separate the corn from the chaff, so God separates between, or investigates, the good and the bad in the daily conduct of men. Hence the Septuagint reads ἐξιχνίασας, “thou hast investigated.” Bishop Hare, who renders “thou dost compass,” supposes it to be a metaphor taken from hunting. “Winnowing,” says Archbishop Secker,” would sound uncouth But Mudge hath hit on the word siftest, which, though an idea somewhat different, suits very well.”
