  5 H3091 and Joshua H559 said H5674 unto them, Pass over H6440 before H727 the ark H3068 of Jehovah H430 your God H8432 into the midst H3383 of the Jordan, H7311 and take you up H259 every H376 man H68 of you a stone H7926 upon his shoulder, H4557 according unto the number H7626 of the tribes H1121 of the children H3478 of Israel;
  6 H226 that this may be a sign H7130 among H1121 you, that, when your children H7592 ask H4279 in time to come, H559 saying, H68 What mean ye by these stones?
  7 H559 then ye shall say H4325 unto them, Because the waters H3383 of the Jordan H3772 were cut off H6440 before H727 the ark H1285 of the covenant H3068 of Jehovah; H5674 when it passed over H3383 the Jordan, H4325 the waters H3383 of the Jordan H3772 were cut off: H68 and these stones H2146 shall be for a memorial H1121 unto the children H3478 of Israel H5704 for H5769 ever.
  8 H1121 And the children H3478 of Israel H6213 did H3091 so as Joshua H6680 commanded, H5375 and took up H8147 twelve H68 stones H8432 out of the midst H3383 of the Jordan, H3068 as Jehovah H1696 spake H3091 unto Joshua, H4557 according to the number H7626 of the tribes H1121 of the children H3478 of Israel; H5674 and they carried them over H4411 with them unto the place where they lodged, H3240 and laid them down there.
  9 H3091 And Joshua H6965 set up H8147 twelve H68 stones H8432 in the midst H3383 of the Jordan, H7272 in the place where the feet H3548 of the priests H5375 that bare H727 the ark H1285 of the covenant H4673 stood: H3117 and they are there unto this day.
