Exactly! And describes the NT Jesus.<quoted text>
Jeremiah 17:10 is talking about Jehovah God the Father who Jesus is the Image of.
Darby Translation (DARBY)
10 I Jehovah search the heart, I try the reins, even to give each one according to his ways, according to the fruit of his doings.
Jesus is God:
Revelation 2:18-29 (Darby)
18 These things says the Son of God, he that has his eyes as a flame of fire, and his feet [are] like fine brass:
19 I know thy works, and love, and faith, and service, and thine endurance, and thy last works [to be] more than the first.
21 And I gave her time that she should repent, and she will not repent of her fornication.
22 Behold, I cast her into a bed, and those that commit adultery with her into great tribulation, unless they repent of her works,
23 and her children will I kill with death; and all the assemblies shall know that I am he that searches [the] reins and [the] hearts; and I will give to you each according to your works.
24 But to you I say, the rest who [are] in Thyatira, as many as have not this doctrine, who have not known the depths of Satan, as they say, I do not cast upon you any other burden;
25 but what ye have hold fast till I shall come.
26 And he that overcomes, and he that keeps unto the end my works, to him will I give authority over the nations,
27 and he shall shepherd them with an iron rod; as vessels of pottery are they broken in pieces, as I also have received from my Father;
28 and I will give to him the morning star.
29 He that has an ear, let him hear what the Spirit says to the assemblies.
