1. Concerning the first, this must of necessity be a certain rule that what the holy and elect Angels do not know, the evil and faln Angels must much more ignore, except the knowledge of evil and guilt, from which the good Angels are free; and these may be reduced to these few points. 1. We here may consider that the knowledge of Angels, is to be restrained into these three ranks; first either their innate and congenerate knowledge, or secondly their infused or revealed knowledge by God in his Son Jesus Christ, or thirdly their experimental knowledge that they gain by observation and experience, and it is of the first only that we speak in this Paragraph, and the rest we shall handle anon. 2. That our cogitations, desires and affections are not known to the Angels, unless they manifest themselves either by external signs, or effects, or be revealed from God; And these ways they may be known, but not otherwise; for it is manifest that Satan had darted it, or put it into the mind of _Judas_ to betray Christ, yet had he so cunningly carried himself, that neither by any effect nor sign did the Disciples know it until our Saviour did reveal it unto them. So that the Scriptures do plainly inform us of the truth in this particular, as, _For what man knoweth the things of a man, save the spirit of man which is in him?_ For this is only proper to God to search the heart, and to understand the cogitations, as saith the Text: _For thou only knowest the hearts of the children of men_, he only knoweth them, and neither Angels nor men: and though the heart be deceitful and desperately wicked, yet _God doth search the heart, and try the reins_. So that if the good Angels do not know the cogitations, desires and affections of Mens hearts, except God either reveal them unto them, or they be made manifest by signs and effects, much less must the bad Angels know or understand them. 3. Those things that are meerly contingent, and those which depend upon free will, cannot be known of the Angels, unless they be revealed by God, as is manifest by the Text. _Produce your cause, saith the Lord, bring forth your strong Idols, or Diviners, saith the King of Jacob. Let them bring them forth, and shew us what shall happen: let them shew the former things what they be, that we may consider them, and know the later end of them, or declare us things for to come. Shew the things that are to come hereafter, that we may know that ye are Gods: yea, do good, or evil, that we may be dismayed, and behold it together._ And as the good Angels know not contingent things, or those that depend upon free will, much less do the faln Angels understand them, as is manifest in these examples. The Angel that was sent of God to warn _Joseph to take the child Jesus, and fly into Ægypt_, did not of his own innate knowledge, either in it self, or in its cause (as the Schoolmen speak) know that _Herod_ would seek the child to destroy him,
