Leviticus 19:24

“But in the fourth year all the fruit thereof shall be holy, etc.] Separated and devoted to the service of God, to be given to the priest, or to be bought again of him; wherefore the Targum of Jonathan adds, at the end of the verse, “redeemed from the priest”, a redemption price being given to the priest; and, as Jarchi observes, as the tithe was not eaten without the walls of Jerusalem, but by redemption, even so likewise this: to praise the Lord [withal]; for his abundant goodness in blessing and making the trees fruitful, and bringing their fruit unto perfection; and by devoting the first fruits to God, his name was praised and glorified, as well as by eating them with joy and gladness…”

“Holy - Consecrated to the Lord, as the first - fruits and tithes were, and therefore given to the priests and Levites, Num 18:12-13; Deu 18:4 yet so that part of them were communicated to the poor widows and fatherless and strangers. See Deu 14:28. To bless the Lord, by whose power and goodness the trees bring forth fruit to perfection. Leviticus 19:25”

“all the: Num 18:12, Num 18:13; Deu 12:17, Deu 12:18, Deu 14:28, Deu 14:29, Deu 18:4; Pro 3:9 holy to praise the Lord withal: Heb. holiness of praises to the Lord Leviticus 19:25”
