Pleasant
Generally, when the Bible describes something as "pleasant" or "desirable," it is talking about true ideas and concepts, things of the intellect. A good example is in Genesis 49:15, where Jacob is prophesying about his son Issachar: "And he saw that rest was good, and the land that it was pleasant..." Here "rest was good" refers to celestial things, or things led by love of the Lord; "the land that it was pleasant" refers to spiritual things, or things led by the understanding of what is true.
