KJV_Strongs(i)
  20 G1063 For G1487 if G668 after they have escaped [G5631]   G3393 the pollutions G2889 of the world G1722 through G1922 the knowledge G2962 of the Lord G2532 and G4990 Saviour G2424 Jesus G5547 Christ G1707 , they are G3825 again G1707 entangled [G5651]   G5125 therein G1161 , and G1096 overcome [G5754]   G2274   [G5736]   G2078 , the latter end G5501 is worse G846 with them G4413 than the beginning.
  21 G1063 For G2258 it had been [G5713]   G2909 better G846 for them G3361 not G1921 to have known [G5760]   G3598 the way G1343 of righteousness G2228 , than G1921 , after they have known [G5631]   G1994 it, to turn [G5658]   G1537 from G40 the holy G1785 commandment G3860 delivered [G5685]   G846 unto them.
  22 G1161 But G4819 it is happened [G5758]   G846 unto them G3588 according to G227 the true G3942 proverb G2965 , The dog G1994 is turned G1909 to G2398 his own G1829 vomit G1994 again [G5660]   G2532 ; and G5300 the sow G3068 that was washed [G5671]   G1519 to G2946 her wallowing G1004 in the mire.
ERV(i) 20 For if, after they have escaped the defilements of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein and overcome, the last state is become worse with them than the first. 21 For it were better for them not to have known the way of righteousness, than, after knowing it, to turn back from the holy commandment delivered unto them. 22 It has happened unto them according to the true proverb, The dog turning to his own vomit again, and the sow that had washed to wallowing in the mire.
