'Six' in the Bible

Now Noah was six hundred years old when the flood of water came upon the earth.

In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on the same day all the fountains of the great deep burst open, and the floodgates of the sky were opened.

Now it came about in the six hundred and first year, in the first month, on the first of the month, the water was dried up from the earth. Then Noah removed the covering of the ark, and looked, and behold, the surface of the ground was dried up.

Then Leah said, “God has endowed me with a good gift; now my husband will dwell with me, because I have borne him six sons.” So she named him Zebulun.

These twenty years I have been in your house; I served you fourteen years for your two daughters and six years for your flock, and you changed my wages ten times.
