act(-ion), deed, doing, invention, occasion, work

Concise Bible Dictionary:

In natural things inventions have much increased since early days. There is no harm in the things themselves; but if they foster the pride of man, and divert him from God, they become the instruments of Satan. Many things also are found in Christendom of which there is not the least mention in scripture. WITTY INVENTIONS in Proverbs 8:1212I wisdom dwell with prudence, and find out knowledge of witty inventions. (Proverbs 8:12) is the same word as that translated “discretion” in Proverbs 1:44To give subtilty to the simple, to the young man knowledge and discretion. (Proverbs 1:4) and Proverbs 2:11,11Discretion shall preserve thee, understanding shall keep thee: (Proverbs 2:11) and others. Fürst gives for Proverbs 8:12,12I wisdom dwell with prudence, and find out knowledge of witty inventions. (Proverbs 8:12)knowledge of intelligent counsels.”
