The heart means love. A good heart means love to the Lord and to the neighbor, while a hard or stony heart means the love of self or the world -- riches and things. When the psalmist asks the Lord to search his heart, he wants the Lord to see what it is that he loves. And we are what we love. What we eat may form our earthly body, but it's only temporary, what we love forms our spiritual body, beautiful or ugly as we have chosen. It's interesting to note that the first multi-cellular motion of our embryo is the pulsating that starts in a twist of blood vessel that is to become our heart, and the last motion of our natural body is our heartbeat. It is there for all of our natural life. And of course there is a beating heart in our spiritual bodies when we come to put them on.

Like most meanings in the Bible this can change depending on context to a meaning perverted into the opposite. Instead of a mind full of knowledge and love of the neighbor, the love can be twisted around to pride in one's own self-intelligence and lead toward evil instead of good. The elders and chief priests who sat in judgment on Jesus in Caiaphas' house show the other side of the representation. Elders are mentioned in the Bible mainly in two ways: First the elders of Israel: and second the 24 elders seated about the throne of God in Revelation. In both cases, they mean wisdom, which comes from using the truths we've learned to do what's right in our everyday lives. The elders of Israel mean the chief things of wisdom in the church called Israel. The elders mentioned in Revelation 4 mean the wisdom of the highest heavens, and by extension the whole of the heavens.
