“Sure,” אָמַן, faithful, as the sun. (Ps. lxxxix. 37.)
“Enlightening,” from אוֹר, to give light, as the sun. (Gen. i. 15, 17, 18; Isa. lx. 19; Ezek. xxxii. 7.)
In B (verses 11, 12, 13),—
“Warned,” from זָהַר, to make light, hence, to teach, admonish.
“Keeping,” from שָׁמַר, to keep, observe, as the heavens. (Ps. cxxx. 6; Isa. xxi. 11.) Or as the heavenly bodies observe God's ordinances.
“Errors,” from שָׁנַה, to wander, as the planets.
“Keep back,” חָשַׂךְ, to hold back, restrain.
“Have dominion over,” from מָשַׁל, to rule. Spoken of the sun and moon in Gen. i. 18. “The sun to rule the day,” &c. (Ps. cxxxvi. 8, 9.)
The other half of the Psalm is just as perfectly arranged. For example, there are six words used (verses 7-9) to describe the fulness of the Word of God, and they are thus placed, alternately:—
F | Two feminine singulars. (Law and Testimony.)
G | One masculine plural. (Statutes.)
F | Two feminine singulars. (Commandment and Fear.)
G | One masculine plural. (Judgments.)
