Charles H. Spurgeon on Psalms 107:12

He brought down their heart with labour. Those towering passions by which they vainly vaunted themselves above the law and the worship of God, he weakened and curbed, so that they began to submit themselves to God. The root enk taken from the Arabic, describes a process of weakening by compressing the wings or shrinking the fingers, and is properly applied to birds, which when their wings are compressed are obliged to fall to the ground, or to men, who by the shrivelling up of their fingers lose the power of working; whence it is transferred to oppressions or depressions of any kind. —Venema.
