Verses 14 and 15 go together, emphasizing Yahweh’s goodness in choosing the Israelites to be his people. The connection between the two verses should be quite clear.
Behold: a way of calling their attention; see 1.10.
To the LORD your God belong heaven and the heaven of heavens: this is a normal Hebrew way of making a superlative, which may not be natural in some languages (as it is not natural in English). The whole phrase means “all the heavens above,” “even the highest heavens.” Revised English Bible has “heaven itself, the highest heaven,” New Jewish Publication Society’s Tanakh “the heavens to their uttermost reaches,” New International Version “the heavens, even the highest heavens.” Some repetition or other form of emphasis seems advisable; but the translator must decide whether a phrase like “even the highest heavens” (Good News Translation) will lead the reader to think that there are a number of heavens, varying in height. BÍBLIA para todos Edição Comum has “the heavens and all they contain.” In many languages “sky” and “heaven” will be the same term; so “the sky and all it contains” or “everything in the sky” will be natural ways to express this. For the LORD your God see 1.6.
The earth with all that is in it: primarily this refers to all the living beings on earth. So we may translate “the earth and all the living things in it.”
