19 H1961 And when H6963 the voice H7782 of the trumpet H1980 sounded H3966 long, and waxed louder H3966 and louder, H4872 Moses H1696 spoke, H430 and God H6030 answered H6963 him by a voice.

20 H3068 And the LORD H3381 came H3381 down H2022 on mount H5514 Sinai, H413 on H7218 the top H2022 of the mount: H3068 and the LORD H7121 called H4872 Moses H7218 up to the top H2022 of the mount; H4872 and Moses H5927 went up.
