My doctrine shall drop as the rain, my speech shall distil as the dew, as the small rain upon the tender herb, and as the showers upon the grass:
My doctrine shall drop ... The language may justly be taken as uttered in the form of a wish or prayer. May my doctrine (discourse) drop as the rain! My speech distil as the dew! Like showers on the tender blade; like copious dew drops х wªkirbiybiym (H7241), multitude of drops] on the grass! [The Septuagint interprets it in the optative mood, prosdokasthoo hoos huetos to apofthengma mou, kai katabeetoo hoos drosos ta reemata mou, hoosei ombros. Ep' agroostin, kai hoosei nifetos epi chorton.] The comparison of wholesome instruction to the pure, gentle, and insinuating influence of rain or dew is frequently made by the sacred writers (Isaiah 5:6; Isaiah 55:10-11). The metaphor was probably borrowed from Egypt, in the hieroglyphic imagery of which the beneficial influence of instruction was symbolized by the representation of a sky-dropping dew.
Verse 3. Because I will publish-for I will proclaim the name of the Lord (cf. Exodus 34:5-7). Some render the word, 'I address you in the name of the Lord.' The announcement of that gracious name, with the attractive attributes of which it is the sign, carries with itself the reason of the sweet simile used in this verse; for as the parched verdure and tender blades are revived by the refreshing influence of the showers or the dew, so the conscience stricken hearts of men receive new life and vigour from the doctrine which proclaims the mercy and the faithfulness of God.
Ascribe ye greatness unto our God х godel (H1433), majesty, royal magnificence; Septuagint, megaloosunee (G3172); (Hebrews 1:3).]
