The color green is almost exclusively used in connection with plants in the Bible, and the meaning is closely connected to the meaning of plants as well. Plants, in general, represent facts, knowledge that we can gather from the world. Green plants are ones that are alive and growing. Since life represents love and goodness, it makes sense that green plants are facts that have the potential for good use. It also indicates that they are the kinds of things we learn through directly through our senses, since to identify green plants we need to actually see the greenness.

'The third day' as in Genesis 22:4, signifies something complete and a beginning of sanctification. 'Day,' in the Word, signifies a state, as do all references to time. When 'third' is added, it signifies the end of that state and the beginning of the following state. In the internal sense of the Word, 'three days' and 'the third day' signify the same thing. The Lord rose again on the third day, which is also why the Lord distinguished the stages of his life into three in Luke 8:32. The Lord also endured the last temptation on the cross, on 'the third hour of the day' in Mark 15:25. In Exodus 19:16, 'the third day' signifies the end of a state of preparation for reception, and so an end of purification. In Hosea 6:2, 8, 'the third day' has the same meaning as 'the seventh day,' which is a state of peace.
