"Adam = man
The Hebrew word Adam means “man.” Adam is also phonetically very close to “adamma,” which means “ground,” from the dust of which Adam was formed (Gen. 2:7)
Seth = appointed, granted, given
After Cain murdered Abel, Eve became pregnant and gave birth to Seth, saying “God hath appointed me another seed instead of Abel, whom Cain slew” (Gen. 4:25). The name Seth means “appointed,” “granted,” or “given.”
Enosh = mortal, frail, feeble
Enosh is from the root anash, meaning incurable, or leading to death, as in a mortal wound, a grief, a woe, a sickness, or a wickedness.
Kenan = Sorrow, dirge, lamentation
The exact meaning of Kenan is obscure, but it possibly means to chant a dirge or lamentation, or to sing a sad song. Other commentators state that the word means “possession.”
Mahalalel = The Blessed God, the Praiseworthy God
The first part of the name, Mahalal, means “blessed” or “praise.” The last part of the name, El, means “God.” (Interestingly, a plural form of El is Elohim, but when used in reference to the Hebrew God does not mean “gods” but “God,” as in Genesis 1:1: “In the beginning, God [Elohim] created the heavens and the earth.”) Hebrew names often incorporate el, as in Daniel, which means “God is my judge.” Mahalalel means the “The Blessed God.”
Jared = Shall come down
The name Jared comes from the very common verb yaradh, which means to come down, go down, or descend, or to leave a prominent place such as a palace.
Enoch = Discipling
The name Enoch comes from the verb hanak meaning to dedicate (or initiate, or inaugurate), as one would dedicate a building, wall, altar, or image, after completing it. (Hanukka, which will be celebrated soon, means “feast of dedication.”) Alternative meanings are to imprint, to instruct, to make wise, and to train, as in, “train up (hanak) a child in the way he should go.” (Prov. 22:6) The derivative hanik means, “trained.” (see, e.g., Gen. 14:14)
Methuselah = His death shall bring
God revealed to Enoch His plan to destroy the world with a Great Flood (PP 85), apparently telling Enoch that as long as his son was alive, God would forbear judgment. Enoch made his son's name a prophecy: “When he dies, it will come” or “his death shall bring it.” If you add up the numerical data given in the chrono-genealogy of Genesis 5, you will see that Methuselah lived until the year of the Flood. (See, e.g., Spirit of Prophecy, v. 1, p. 170: “Methuselah, the grandfather of Noah, lived until the very year of the flood; and there were others who believed the preaching of Noah, and aided him in building the ark, who died before the flood of waters came upon the earth.” ) Methuselah's name is thus a prophecy within a prophecy.
Think about the fact that Methuselah lived longer than any other man who ever lived and died (969 years) in conjunction with the prophetic aspect of his name. God stated that he would bring the Flood at the end of Methuselah's life, then He made Methuselah the longest-lived man in history. Truly, God is “slow to anger, abounding in love and forgiving sin and rebellion. Yet he does not leave the guilty unpunished” (Num. 14:18). “God is long suffering toward us, not willing that any should perish but that all should come to repentance” (2 Peter 3:8-10)."
