Daniel, in the close, when he ends that matter, tells us what impressions this vision made upon him; it overwhelmed his spirits to such a degree that his countenance was changed, and it made him look pale; but he kept the matter in his heart. Note, The heart must be the treasury and store-house of divine things; there we must hide God's word, as the Virgin Mary kept the sayings of Christ, Luke ii. 51. Daniel kept the matter in his heart, with a design, not to keep it from the church, but to keep it for the church, that what he had received from the Lord he might fully and faithfully deliver to the people. Note, It concerns God's prophets and ministers to treasure up the things of God in their minds, and there to digest them well. If we would have God's word ready in our mouths when we have occasion for it, we must keep it in our hearts at all times.
