They are created now, i.e. revealed unto thee by me; brought to light, as things are by creation. Things are frequently said to be made or done in Scripture, when they are declared or manifested. Job 5:3, I cursed, i.e. I pronounced it cursed. Psalms 2:4, That thou mightest be justified, i.e. declared and acknowledged to be just. Hosea 5:15, Till they acknowledge their offence; which in the Hebrew is, till they be guilty. Not from the beginning, Heb. not from thence; not from these ancient times, when other things were revealed unto thee. Even before the day, Heb. and (or, or, as this particle is frequently used) before this day. Such pronouns are oft understood, as we have seen; and this day answers to nor in the first clause; and this clause seems to be added as an exposition of the next foregoing clause, which is more general and ambiguous, not from then or before this day. When thou heardest them not, Heb. and thou didst not hear them, to wit, before this time, in which God hath revealed them to time by my ministry. Lest thou shouldest say, Behold, I knew them; either by thine own sagacity, or by the help of thine idols. The sense is, That it might appear that thou hadst the knowledge of these things only from me, who made known unto thee only what and when I pleased.
