  22 H4872 And Moses H3478 led Israel H5265 onward H5488 from the Red H3220 Sea, H3318 and they went out H4057 into the wilderness H7793 of Shur; H3212 and they went H7969 three H3117 days H4057 in the wilderness, H4672 and found H4325 no water.
  23 H935 And when they came H4785 to Marah, H3201 they could H8354 not drink H4325 of the waters H4785 of Marah, H4751 for they were bitter: H8034 therefore the name H7121 of it was called H4785 Marah.
  24 H5971 And the people H3885 murmured H4872 against Moses, H559 saying, H8354 What shall we drink?
  25 H6817 An he cried H3068 unto Jehovah; H3068 And Jehovah H3384 showed H6086 him a tree, H7993 and he cast H4325 it into the waters, H4325 and the waters H4985 were made sweet. H7760 There he made H2706 for them a statute H4941 and an ordinance, H5254 and there he proved them;
  26 H559 and he said, H8085 If thou wilt diligently H8085 hearken H6963 to the voice H3068 of Jehovah H430 thy God, H6213 and wilt do H3477 that which is right H238 in his eyes, and wilt give ear H4687 to his commandments, H8104 and keep H2706 all his statutes, H7760 I will put H4245 none of the diseases H7760 upon thee, which I have put H4714 upon the Egyptians: H3068 for I am Jehovah H7495 that healeth thee.
