An image. — An image in the Hebrew is teraphim — a plural form, but used as a singular. We have no instance of the singular. The Latin equivalent, “penates,” singularly enough, is also only found in the plural form. In this case, probably, it was a life-size figure or bust. The word has been discussed above (1 Samuel 15:23). It is singular how, in spite of the stern command to avoid idolatry, the children of Israel seemed to love to possess these lifeless images. The teraphim were probably a remnant of the idolatry originally brought by some of Abraham’s family from their Chaldaean home. These idols, we know, varied in size, from the diminutive image which Rachel (Genesis 31:34) was able to conceal under the camel saddle to the life-size figure which the Princess Michal here used to make her father’s guards believe that her sick husband, David, was in bed. They appear to have been looked on as tutelary deities, the dispensers of domestic and family good fortune. It has been suggested, with some probability, that Michal, like Rachel, kept this teraphim in secret, because of her barrenness.
A pillow of goats’ hair. — More accurately, a goat’s skin about its head. So render the Syriac and Vulgate Versions. The reason of this act apparently was to imitate the effect of a man’s hair round the teraphim’s head. Its body, we read in the next clause, was covered “with a cloth.” Some scholars have suggested that this goat’s skin was a net-work of goat’s hair to keep off the flies from the supposed sleeper. The LXX., instead of k’vir (skin), read in their Hebrew copies keaved (liver). As the vowel points were introduced much later, such a confusion (especially as the difference between d and r in Hebrew is very slight) would be likely enough to occur in the MSS.
Josephus, adopting the LXX. reading, explains Michal’s conduct thus — “Michal put a palpitating goat’s liver into the bed, to represent a breathing sick man.”
With a cloth. — Heb., beged. This was David’s every-day garment, which he was in the habit of wearing. This, loosely thrown over the image, would materially assist the deception. The fifty-ninth Psalm bears the following title — “A michtam(or song of deep import) of David, when Saul sent, and they watched the house to kill him.” The internal evidence, however, is scarcely confirmatory of the accuracy of the title. The sacred song in question is very probably one of David’s own composition, and it is likely enough that the danger he incurred on this occasion was in his mind when he wrote the solemn words; but there are references in this psalm which must apply to other events in his troubled, anxious life.
