1 Kings 20:22

Go, strengthen thyself ... - That is, “collect troops, raise fortifications, obtain allies ... take all the measures thou canst to increase thy military strength. Be not rash, but consider well every step ... for a great danger is impending.”

At the return of the year - i. e., “When the season for military operations again comes round.” The wars of the Oriental monarchs at this time, like those of early Rome, were almost always of the nature of annual incursions into the territories of their neighbors, begun in spring and terminating in early autumn. Sustained invasions, lasting over the winter into a second or a third year, are not found until the time of Shalmaneser 2 Kings 17:5; 2 Kings 18:9, and do not become common until the Median and Babylonian period.
