Then I proclaimed a fast there, at the river of Ahava, that we might afflict ourselves before our God, to seek of him a right way for us, and for our little ones, and for all our substance.
Ver. 21. Then I proclaimed a fast there] A day of restraint from food, fine clothes, and other delights of life. There is a threefold fast, saith one, from meat, from mirth, and from sin; this last crowns all. Unless God sees turning, he sees no work in a fast, saith another, explaining that text, John 3:10, "God saw their works, that they turned." Of a fast, See Trapp on " Joe 2:12 ".
That we might afflict ourselves before our God] Not outwardly only (that is but the shell, Isa 58:3), but inwardly also, for that is the kernel of this exercise, Jeremiah 16:19, which else is but bodily, and profiteth little; something it may, as it did Ahab; but if rightly performed, though it weakeneth the body, yet it strengtheneth the spirit, making it vigorous and victorious.
To seek of him a right way for us] To edge our prayers and give wings to them; for fasting inflameth prayer, and prayer sanctifieth fasting; hence they go coupled for the most part, Luke 2:37 Matthew 17:21 1 Corinthians 7:5. And surely, if with fasting and prayer we can seek of God direction and protection, as here, we shall speed of both.
And for our little ones] These should be a main part of our care, to lay up prayers for them, to commend them to God's safe keeping, forasmuch as puerilitas est periculorum pelagus, Little ones are liable to a thousand deaths and dangers.
And for all our substance] Our stock and our store, all the goods that we have got and gathered together. Our English word Riches answereth to the Hebrew Recush.
