'Pleasantness' in the Bible

If they listen and serve [him], they complete their days in prosperity and their years in pleasantness.

Her ways [are] ways of pleasantness, and all her paths [are] peace.

Perfume and incense will gladden a heart, and the pleasantness of one's friend [is] {personal advice}.

For you have forgotten the God of your salvation, and you have not remembered the rock of your refuge; therefore you plant plants of pleasantness, and you {plant} a vine of a foreigner.
