Hi; Lamech died 5 years before the flood at 777 years of age,the numbers '5777' are associated or ties in with the word 'sorrow'. This is the Hebrew year 5777 [2017].Methuselah named his son 'sorrow' Why? because he knew all about the coming flood and knowing the many people that would die, but I'm afraid this could have a 'double fulfillment' because we are living at the end of this age with the year numbers 777,remember as it was in the days of Noah.We need to watch if this Hebrew year 5777 will be a time of 'sorrow'. We could have a 'full blown war' at anytime,really anywhere 'sorrow' can overtake this world in one day. Many will be Left behind after the rapture and that qualifies for 'sorrow' as well. We have had many signs before this Hebrew year 5777.I take this word 'sorrow' very seriously.It was a very somber find for me to know what 'Lamech' name really means. We need to brace ourselves for whatever comes our way by having a relationship with Jesus.
