A careful examination of Hebrews 7 will show that the one who "receives tithes" is Melchizedek, not Jesus.
"1 For this
Melchizedek, king of Salem, priest of the Most High God, who met Abraham as he was returning from the slaughter of the kings and blessed him, 2 to whom also Abraham apportioned a tenth of all
the spoils, was first of all, by the translation
of his name, king of righteousness, and then also king of Salem, which is king of peace. 3 Without father, without mother, without genealogy, having neither beginning of days nor end of life, but
made like the Son of God, he remains a priest perpetually."
Melchizedek was made like the Son of God, not the other way around. Melchizedek remains a priest perpetually, just as Jesus is a priest perpetually.
"4 Now observe how great this man [Melchizedek] was to whom Abraham, the patriarch, gave a tenth of the choicest spoils. 5 And those indeed of the sons of Levi who receive the priest’s office have a commandment [
a]in the Law to collect [
b]a tenth from the people, that is, from their countrymen, although they [
c]are descended from Abraham. 6 But the one [Melchizedek] whose genealogy is not traced from them collected [
d]a tenth from Abraham and [
e]blessed the one who had the promises. 7 But without any dispute the lesser
person is blessed by the greater. 8 In this case mortal men receive tithes, but in that case one [Melchizedek]
receives them, of whom it is witnessed that he lives
on. 9 And, so to speak, through Abraham even Levi, who received tithes, has paid tithes, 10 for he was still in the loins of his [
f]forefather when Melchizedek met him."
I have added Melchizedek in square brackets only to emphasize the fact that he is the subject. This is all about Melchizedek,
not about Jesus. Only by not paying attention to the subject of the passage can one conclude that Jesus still receives tithes.
"11 So if perfection was through the Levitical priesthood (for on the basis of it the people received the Law), what further need
was there for another priest to arise according to the order of Melchizedek, and not be designated according to the order of Aaron? 12 For when the priesthood is changed, of necessity there takes place a change of law also. "
Note that last phrase...
a change of the law also. The change
to the Levitical priesthood came with a change of law, and the change
to the priesthood of Jesus Christ came with a change of law also. Christians aren't under the Mosaic law.
"13 For the one about whom these things are said belongs to another tribe, from which no one has officiated at the altar. 14 For it is evident that our Lord [
g]was descended from Judah, a tribe with reference to which Moses said nothing concerning priests. 15 And this is clearer still, if another priest arises according to the likeness of Melchizedek, 16 who has become
a priest not on the basis of a law of [
h]physical requirement, but according to the power of an indestructible life. 17 For it is attested
of Him,
'You are a priest forever
According to the order of Melchizedek.'"
Here is where Jesus becomes the subject.
"18 For, on the one hand, there is
the nullification of a former commandment because of its weakness and uselessness 19 (for the Law made nothing perfect); on the other hand,
there is the introduction of a better hope, through which we come near to God. "
Note again the change of the Law.
"20 And to the extent that
it was not without an oath 21 (for they indeed became priests without an oath, but He with an oath through the One who said to Him,
“The Lord has sworn
And will not change His mind,
‘You are a priest forever’”);
22 by the same extent Jesus also has become the [
i]guarantee of a better covenant."
... a better covenant of which tithing is not part.
Poor hermeneutics, careless reading, and preconceived notions lead to that erroneous conclusion that Jesus still receives tithes. This passage does not teach that. Further, it emphasizes and repeats that we (Christians) are
not under the old covenant.
