Wilson's Dictionary of Bible Types [1]

 Genesis 49:25 (c) The teaching here probably is that the Lord will grant fruitfulness and that the children given by GOD's kindness will be fed, well cared for, and will grow to maturity as they should.

 Exodus 29:27 (c) This part of the animal is typical of our affection and love offered to GOD, waved before Him as a memorial, and to remind Him that we love Him above all others. We believe that all the "burnt" offerings teach this same truth.

 Job 21:24 (a) We are taught by this figure that this person retained his vigor, power and resourcefulness until the end of his days.

 Song of Solomon 1:13 (b) Here is a picture of the perfect love, sweetness and satisfaction which exists between the Lord and His bride, the children of GOD.

 Song of Solomon 4:5 (b) This will remind us of the sufficiency, devotion and activity of the love of the children of GOD for the Lord Jesus Christ (See also  Song of Solomon 7:7-8).

 Song of Solomon 8:8 (b) This peculiar picture will remind us that the Christian may lose his love and affection for the bridegroom, the Saviour. Or it may be that this bride is a very young bride who has not yet learned to love, worship and adore as she should. Love grows as it is practiced. It may also be that this is the Christian who has lost his first love, and is not now as affectionate as she should be. Evidently this lack is made up and is restored as described in verse10.

 Isaiah 28:9 (a) We learn from this comparison that some of GOD's people grow up to maturity as Christians. They no longer need to feed on milk, but are able to eat and digest strong meat. Paul mentions this same truth in1Co  3:2. Christians should grow in the knowledge of the things of GOD until they become matured Christians. (See  Ephesians 4:13).

 Isaiah 60:16 (a) GOD's people were to obtain the best and richest treasures of their enemies. Their enemies would be made to give up their very living to Israel.

 Isaiah 66:11 (a) This is a prophecy of the restoration of Jerusalem when Israel will again rejoice in the abundant blessings of GOD as the babe is satisfied with the mother's milk.

 Ezekiel 23:3 (a) This is a terrible accusation against Israel because they had permitted the wicked people around them to take liberties with them to satisfy all their evil desires. Israel committed horrible sins with the wicked nations around them. In verses  Ezekiel 23:8 and  Ezekiel 23:34 we find that these same nations punished Israel severely.

 Hosea 2:2 (a) GOD presents to us a graphic picture of the wicked associations of Israel with the idolatrous nations around her. GOD would not ignore these evil associations. We find this same sin presented in all of its evil in the church of Rome today. They have partaken of the idolatrous practices of almost every known evil religion. They nourish every form of evil and sin and promote every kind of wicked association with the world.

 Hosea 9:14 (a) GOD is warning Israel that He will punish them by preventing the blessings which they expected to receive and would dry up their natural resources of sustenance.

 Nahum 2:7 (b) Here we find revealed that in the day of GOD's judgments many will be calling for help and will cry out for relief when none is available.

 Revelation 15:6 (a) This probably teaches us the fact that these angels had their loyalty, their love and their devotion bound up in the golden bands of purity and holiness. They were entirely loyal to GOD, He had their love and affection.
