'First' in the Bible

{And it was} in the fortieth year, on the eleventh month, on [the] first [day] of the month, Moses spoke to the {Israelites} according to all that Yahweh had instructed him [to speak] to them.

And he wrote upon the tablets {according to the first writing}, the ten words that Yahweh spoke to you on the mountain from the midst of the fire on the day of the assembly, and Yahweh gave them to me.

But you shall certainly kill him; your hand shall be first against him to kill him and next the hand of all [of] the people.

And leaven shall not be seen with you in any of your territory for seven days, and none of the meat that you will slaughter on the evening on the first day shall remain overnight until morning.

The hand of the witnesses shall be first against the person to kill the person, and afterward the hands [of] all the people, and [so] you shall purge the evil from your midst.

her first husband who sent her [away] is not allowed {to take her again} to become a wife to him after she has {been defiled}, for that [is] a detestable thing {before} Yahweh, and [so] you shall not mislead into sin the land that Yahweh your God [is] giving to you [as an] inheritance.
