Genesis 19:34

34 And the tother day the more daughter said to the less, or the younger (one), Lo! I slept yesterday with my father; give we to him to drink wine also in this night; and thou sleep with him, that we save the seed of our father. (And the next day the elder daughter said to the younger one, Lo! yesterday I slept with my father; tonight we shall also give him some wine to drink, and then thou sleep with him, so that we shall most assuredly save our father's seed, or our father's family.)

Genesis 19:34 Meaning and Commentary

Genesis 19:34

And it came to pass on the morrow
The day following the night, in which the above was transacted: that the firstborn said to the younger, behold, I lay yesternight with
my father;
informed her, that what they had contrived succeeded according to their wish, and therefore, for her encouragement to go on, proposes to take the same method again: let us make him drink wine this night also, and go thou in [and] lie
with him, that we may preserve seed of our father;
may have children by him, and so our family be kept up, from whence it may be hoped the Messiah will spring, (See Gill on Genesis 19:32).

Genesis 19:34 In-Context

32 come thou, make we him drunken of wine, and sleep we with him, that we may keep the seed of our father. (come thou, make we him drunk with wine, and sleep we with him, so that we can keep our father's seed, or our father's family, alive.)

33 And so they gave to their father to drink wine in that night (And so that night they gave their father some wine to drink), and the more, or the elder, daughter entered, and slept with her father; and he feeled not, neither when the daughter lay down, neither when she [a]rose.

34 And the tother day the more daughter said to the less, or the younger (one), Lo! I slept yesterday with my father; give we to him to drink wine also in this night; and thou sleep with him, that we save the seed of our father. (And the next day the elder daughter said to the younger one, Lo! yesterday I slept with my father; tonight we shall also give him some wine to drink, and then thou sleep with him, so that we shall most assuredly save our father's seed, or our father's family.)

35 And they gave to their father also in that night to drink wine, and the less daughter entered, and slept with him; and soothly he feeled not then when she lay down, neither when she [a]rose. (And so also that night they gave their father some wine to drink, and the younger daughter entered, and slept with him; and truly he felt nothing when she lay down, nor when she arose.)

36 Therefore the two daughters of Lot conceived of their father. (And so Lot's two daughters conceived by their father.)
