CKJV_Strongs⁽ⁱ⁾

3 G2532 And G2036 said, G281 Truly G3004 I say G5213 unto you, G1437 Except G3361 G4762 you be converted, G2532 and G1096 become G5613 as G3813 little sons, G1525 you shall G3756 not G3361 G1525 enter G1519 into G932 the kingdom G3772 of heaven.

4 G3748 Whoever G3767 therefore G5013 shall humble G1438 himself G5613 as G5124 this G3813 little child, G3778 the same G2076 is G3187 greatest G1722 in G932 the kingdom G3772 of heaven.
