"What is your delight"

But his DELIGHT is in the law of the Lord; and in his law doth he MEDITATE DAY and NIGHT.
And HE SHALL BE LIKE A TREE PLANTED BY THE RIVERS OF WATER, that BRINGETH FORTH HIS FRUIT IN HIS SEASON; HIS LEAF ALSO SHALL NOT WITHER; AND WHATSOEVER HE DOETH SHALL PROSPER. Psalms 1:2,3

Notice: his (your) deight (pleasure or desire) is in (enclosed, wrapped). the law (stature) of the Lord (self existent) and in (enclosed or wrapped up in) his law doth he Meditate (to murmur in pleasure or anger; to ponder :- imagine, roar).
day and night (this represents seasons and a space of time)
And he shall (covenant word) be like a tree (firmness) planted (to transplant, to move from one place to another) by the rivers of water, that bringeth forth his fruit (be,fruitful, grow, increase). in his season (confirmation of the meditation of the day and night) His leaf (to ascend, be high or active mount) also shall not wither; and whatsoever he doeth (ETH=continual repeatedly) shall prosper.
