AKJV_Strongs(i)
  15 H7819 Then they killed H6453 the passover H702 on the fourteenth H6240 H8145 day of the second H2320 month: H3548 and the priests H3881 and the Levites H3637 were ashamed, H6942 and sanctified H935 themselves, and brought H5930 in the burnt H1004 offerings into the house H3068 of the LORD.
  16 H5975 And they stood H5977 in their place H4941 after their manner, H8451 according to the law H4872 of Moses H376 the man H430 of God: H3548 the priests H2236 sprinkled H1818 the blood, H3027 which they received of the hand H3881 of the Levites.
  17 H7227 For there were many H6951 in the congregation H6942 that were not sanctified: H3881 therefore the Levites H5921 had the charge H7821 of the killing H6453 of the passovers H3605 for every H2889 one that was not clean, H6942 to sanctify H3068 them to the LORD.
  18 H4768 For a multitude H5971 of the people, H7227 even many H669 of Ephraim, H4519 and Manasseh, H3485 Issachar, H2074 and Zebulun, H2891 had not cleansed H3588 themselves, yet H398 did they eat H6453 the passover H3808 otherwise H3789 than it was written. H2396 But Hezekiah H6419 prayed H559 for them, saying, H2896 The good H3068 LORD H3722 pardon H3605 every one
  19 H3559 That prepares H3824 his heart H1875 to seek H430 God, H3068 the LORD H430 God H1 of his fathers, H2893 though he be not cleansed according to the purification H6944 of the sanctuary.
