What is grave soaking/ grave sucking /mantle grabbing?

from the old testament

• Supporters of grave soaking often point to an Old Testament verse to defend the practice: the account of a dead man returning to life when his body touched the bones of Elisha (2 Kings 13:21). But this passage describes a one-time miracle intended to display God’s power. There is nothing in the account that suggests that this happened with others or that others should expect the same ability as Elisha.
• Others appeal to the moment when Elisha received Elijah’s mantle (2 Kings 2:1–14). Yet Elijah’s cloak was simply a symbolic sign that God had appointed Elisha as the next prophet.
• Grave soaking rests on a mistaken view of the human spirit. The Bible teaches that when a person dies, the body returns to dust, and the spirit returns to God (Ecclesiastes 12:7). There is nothing spiritual remaining in the physical body left behind, so there is no anointing or power left behind to “absorb.” The practice assumes a kind of spiritual residue in the dead, which contradicts the Bible.
• As to purification in the Law, Numbers 19:16 states that, “Whoever in the open field touches someone who was killed with a sword or who died naturally, or touches a human bone or a grave, shall be unclean seven days.” Rather than becoming spiritual, priests become unclean when coming in contact with the dead or the grave.
• Beyond the questionable and spurious use of the Old Testament to support these practices, there’s a deeper concern. The Bible strongly warns against any form of necromancy. For example, Deuteronomy 18:10–12 reads, “There shall not be found among you anyone who burns his son or his daughter as an offering, anyone who practices divination or tells fortunes or interprets omens, or a sorcerer or a charmer or a medium or a necromancer or one who inquires of the dead, for whoever does these things is an abomination to the LORD” (cf. Leviticus 20:6). While grave soaking does not always involve explicit communication with the dead, its attempt to draw spiritual power from them moves dangerously close to the occult. At best, this practice is a misuse of Scripture. At worst, it’s an indication of something far darker.

from the new testament

• Nothing in the New Testament supports the notion of grave soaking. Instead, Scripture teaches that to be absent from the body is to be present with the Lord (2 Corinthians 5:8; Philippians 1:23). When someone dies, their immaterial part (soul and spirit) is no longer on earth.
• Instead of gaining spiritual power through some kind of transfer, the New Testament explains that all spiritual life and power come from the Holy Spirit, who is given to every believer at conversion. Believers are sealed by the Spirit (Ephesians 1:13), indwelt by Him (Romans 8:9), and strengthened by His ongoing work (Galatians 5:22–23). This means that spiritual growth, gifting, and empowerment are tied to one’s relationship with God. There is not even a hint of the Apostles' or early church teaching that additional power is found in the dead.

implications for today

The practices commonly called grave soaking, grave sucking, or mantle grabbing all refer to various ways that a living person can receive spiritual power or anointing from someone who has died by touching or lying on that person’s grave.

Practices like grave soaking must be taken seriously because Scripture warns God’s people to avoid anything that resembles involvement with the dead. God has given you His Word and His Spirit, and He never directs you to seek power or insight from departed believers. Whenever teaching encourages methods that Scripture never describes and begins pointing you towards ideas rooted in superstition, be forewarned: there’s a danger lurking in those teachers.

You are called to be discerning. Allow Scripture to train you to recognize truth. In it, you will find God’s character, His commands, His promises, and the way He works in the lives of His people. As you read it, you learn what is right, what is false, and how to walk faithfully with God in daily life. Allow the Spirit to use His Word to strengthen your faith and protect you, giving you wisdom to stay grounded in what God has revealed.
