didst set thine heart to understand - what shall come to pass to thy people at the last times (compare Dan 10:14).
chasten thyself - (Dan 10:2, Dan 10:3).
thy words were heard - (Act 10:4). Prayer is heard at once in heaven, though the sensible answer may seem to be delayed. God’s messenger was detained on the way (Dan 10:13) by the opposition of the powers of darkness. If in our prayers amidst long protracted sorrows we believed God’s angel is on his way to us, what consolation it would give us!
