Charles H. Spurgeon on Psalms 119:160

Thy word is true from the beginning. Literally, "The beginning of thy word is truth, "in antithesis to the "enduring for ever, "in the future, in the next clause. Cocceius and Hengstenberg take it, "The sum of thy word is true, "as in Numbers 26:2 Numbers 26:31:26. But the antithesis noticed above in the English version is thus lost; and the old versions support the English version. Also, if it were "the sum, " the plural ought to follow, viz., "of thy words, "not "word." A. R. Fausset.
