Etymology
The meaning of the name could be translated as "the shining one of El." The King James Version spells his name Mahalaleel in the Old Testament and Maleleel in the New Testament.Biblical narrative
Mahalalel was born when his father Kenan (Adam's great-grandson through Seth) was 70 years old. He was one of many children of Kenan. (Genesis 5:12-13; 1 Chronicles 1:2; Jubilees 4:14 Luke 3:37). 
When he was aged 54-60, Mahalalel married Dinah, the daughter of his paternal uncle Barakiel. At the age of 65, he fathered Jared (when the Watchers "descended on the earth" as per Jubilees 4:15). He fathered many other children after that point (Genesis 5:15-16).  
At the age of 227, he became a grandfather to Jared's son Enoch (Genesis 5:18), who was born through Baraka, the daughter of Mahalalel's brother Râsûjâl (Jubilees 4:16). 
Sometime before he turned 292, Mahalalel explained to Enoch the first of the two dream visions the latter had, as recounted through the perspective of Enoch:I had laid me down in the house of my grandfather Mahalalel, (when) I saw in a vision how the heaven collapsed and was borne off and fell to the earth. And when it fell to the earth I saw how the earth was swallowed up in a great abyss, and mountains were suspended on mountains, and hills sank down on hills, and high trees were rent from their stems, and hurled down and sunk in the abyss. And thereupon a word fell into my mouth, and I lifted up (my voice) to cry aloud, and said: 'The earth is destroyed.' And my grandfather Mahalalel waked me as I lay near him, and said unto me: 'Why dost thou cry so, my son, and why dost thou make such lamentation?' And I recounted to him the whole vision which I had seen, and he said unto me: 'A terrible thing hast thou seen, my son, and of grave moment is thy dream-vision as to the secrets of all the sin of the earth: it must sink into the abyss and be destroyed with a great destruction. And now, my son, arise and make petition to the Lord of glory, since thou art a believer, that a remnant may remain on the earth, and that He may not destroy the whole earth. My son, from heaven all this will come upon the earth, and upon the earth there will be great destruction'. After that I arose and prayed and implored and besought, and wrote down my prayer for the generations of the world...
When Mahalalel was 840, his 962-year-old father Kenan died (Genesis 5:14). Mahalalel lived 55 more years after this and died at 895 (Genesis 5:17), placing him eighth in the records for the unusually long lifespans for the antediluvian patriarchs.  
At the time of Mahalalel's death, Noah was 234 as per the Masoretic chronology.
